HOW RADIO WAVES WORK - Science at Home - episode 4

[@user-nq7xl5ew5h]

What a wonderful creative you are!, I've never seen a person explaining waves and knows exactly what I want to learn. Thank you as big as the sky

[@fenways6260]

This is by far the most helpful video on radiowaves.

[@srikanthgokarakonda3490]

Excellent. This video is for both adults and kids. Thank you so much for making this

[@kamis2070]

Thank you! I'm not sure why I have been struggling with this concept, but you have given the best explanation by far!

[@jeanscott5478]

Very easy to understand your explanation. Excellent lesson on radio waves!

[@phomzaraboon7688]

Honestly the best science explanation I've ever watched on the internet!!! and I don't consider myself to be good at science but I understood EVERYTHING!!! Thank you... Let's spread this gospel!!!

[@dannickstrom469]

Thank you so much! So glad you enjoyed it! We actually have more videos on our other KZbin channel! You can find it here! 🙂 kzbin.info/aero/PL9_FktE0pHjpp6NEnJDiIlieKKTz7u_67

[@PinkeySuavo]

Although I excepted it to go more into details, it is a very good and nicely explained introduction!

Brilliant man, I love this!

Underrated, I learned so much and I have difficulities with physics! Thank youuuu

[@dannickstrom469]

Thanks a lot. I'm glad it was able to help! :-)

Excellentop , what a star.😊

[@frankmason1472]

Wow. Just… wow! Thank you! You did a perfect job explaining this to me in very slow methodical language that I could understand. You’re a really great teacher.

[@dannickstrom469]

Thank you so much for the kind words. So happy that you enjoyed it!

[@Abeocanto]

This was a great explanation. I appreciated the examples of frequencies while with the “boat” haha thank you!! (Now I need to understand how is that frequency carrying an specific sound or image)

[@dannickstrom469]

Thank you for you kind comment! The info is carried by "frequency modulation" (for FM radio anyway). This means the frequency is always changing slightly. These very fast, small changes in frequency are a type of code that contains the information to create the audio or image. Kind of like the 1s and 0s of binary code for computers. I hope that makes sense!

[@kiwinesss]

Excellent, you are good at this!!!! Please make more, please!!!

[@kiwinesss]

Could you possibly explain aerodynamics?

[@dannickstrom469]

@@kiwinesssThanks a lot! I'm glad you enjoyed it! I'm actually in the middle of writing a science TV series and one of the episodes is about aerodynamics! Perhaps it can make it onto youtube at some point. :-)

[@savvythefieldhockeyqueen5398]

This was so helpful for me to understand for my homeschool project, thank you!!!

hello,you are player hockey field?

[@mikedonovan4768]

Nice one Mate ! 👍

[@lerkkweed]

Marvellous! Explained these concepts so well to a neophyte like myself.

[@justcurious1940]

A wave is a wave, Light is light , what do u mean light is a wave ? just kidding Thanks for this wonderful video.

[@dianadmitrieva5609]

Thank you so much! Now I can explain it to my 5 year old. Btw your baby is amazing

[@prabhakarsingh9383]

Wow ..just wow ..

[@petya__]

Thanks for the great explanation! And your video quality is amazing :)

[@MahdiHaeri]

thank you, so clearly and simply explained 🔥🔥🔥

[@leonadrian7257]

Thanks!

[@n.l3176]

Great video I will recommend this video to many people

[@tenacresofrandom-ness1236]

That was an awesome and interesting explanation. Thank you!!!!!!

[@and0rew]

Next level explanation. So good

[@thehacknologist1692]

Thx man keep up the good work

[@alta9dena]

Slightly wrong on the description of amplitude, although the gist of the message is correct. If one measures peak-to-peak the value obtained is roughly TWICE the amplitude of a wave. Amplitude is measured from the zero signal level to the peak of the wave (either at the "top of the hill" (positively) or at the "bottom of the valley" (negatively).

[@dannickstrom469]

Yes, you're correct. That must have been a slip of the tongue. Thanks for pointing it out! Although you also have a mistake in your correction! 😂 You must have meant to say "if one measures peak to trough". That would Indeed give you twice the amplitude. See, we're all only human! 😂

[@alta9dena]

Yikes, we're in trouble.

[@prabhakarv4193]

Very nice

Life is a Wave 😌

[@sophiea4411]

This video is 10 millions times better with a cute baby in it

[@dannickstrom469]

I'll tell him that! He's a toddler now and will be super happy to know he has a fan out there! 😊😊

Great explain even non engineering people can also an knowledge 🎉

Nice explanation

[@kimokimo-se3ur]

very creative !! thanks for your effort !!

[@lydiaasante9695]

Thats so helpful really enjoyed that thanks..

[@kenelytics6754]

Nice explanation bro

[@goktugyilmaz1504]

That is also awesome. However, why do low frequency signals be able to pass the walls? It was interesting. I hope you will earn more followers.

[@dannickstrom469]

Apologies, I only saw your comment now! Thanks for your message! The ability for an electromagnetic wave to pass through an object typically depends on the relationship between the wavelength of the wave and the object it meets. If the object is considerably smaller than the wavelength then the wave will not be blocked by it. However this is only a general rule. It also depends on the atomic structure of the particular atoms that make up the object. For instance, certain materials will let light aps through and certain will block it. Perhaps I can explain all of this in more detail in a future episode! :-)

[@chrishipskind6203]

That was so well done.. you are amazing! I will share this with my students.

[@dannickstrom469]

[@seanogrady2629]

7:08 Nice video! Is there something that produce or create these low frequency light waves similar to how a light bulb produces light when it is turned on?

[@dannickstrom469]

Thanks! Yep, it's the motion of electrons up and down an antenna that creates the waves. By adjusting the speed of their motion you control the frequency of radio waves produced. And by "tuning in" the frequency on your radio, the antenna on your radio only looks for that specific frequency. Hope that answers your question!

[@Test-ij6os]

But isnt the electromagnetic spectrum VIBGYOR frequency wise?

[@akbar5088]

Hi iam your subscriber from India 🇮🇳😊 I can easily understand science that you teach than my school teacher make more videos

Thank you so much! I have some new projects in the works and haven't been on KZbin so much. But I do plan to try and upload some more content soon!

[@raehanisiwaqalala282]

Sir what converts electromagnetic waves into electric signals

[@prassanna369]

Great video! I need to know what is the particle nature of radio waves? All says it is photon. But how datas are modified as photon? I won't believe that radios are photons!

[@dannickstrom469]

Hi. Glad you enjoyed it! :-) Radio waves can indeed be thought of as particles (just like any electromagnetic waves). We do indeed call these particles "photons". When you speak of "modifying data" for the radio, I assume you mean, how do we transmit audio information via radiowaves. It is either frequency modulated (FM) or amplitude modulated (AM). From a particle perspective that just means the following: for FM - Variations in the *energy* of the streams of photons hitting the antenna contain the information which can be reconstructed as sound. For AM - Variations in the *quantity* of photons arriving per second contain the information that can be reconstructed as sound. I hope that answers your question, and apologies if I misunderstood what you were asking!

[@prassanna369]

@@dannickstrom469 Thank you sir!

[@davidginono625]

Does the radiowave creat current to run through the antenna? If so does it do so to any arbitrary wire or conductor in our environment?

[@dannickstrom469]

Excellent question. Yes it does. That's how the signal gets to your radio. And yes, the same will happen for any wire or conductor. The radio antenna is just designed to do it most efficiently, and as you "tune the dial" on the radio you are choosing specific frequencies to focus on.

[@davidginono625]

So there are currents in every wire or conductor, such that if we put a voltmeter at the ends of the conductor we can get a flick right😅

[@dannickstrom469]

@@davidginono625 It would be a very small current and very very noisy, as it is a combination of many many countless frequencies all jumbled up together! But I believe you're technically correct! 🙂

[@borress.9269]

how do radio waves signals interrupted by electric fields?

[@georgeedwardscott8161]

no such thing as a wave. a wave is what something does so what is waving?
