EM spectrum: radio wave, infrared, visible light, ultraviolet, X and Gamma ray

Today, my topic is electromagnetic (EM) spectrum, and their uses.
At any single moment, we are surrounded with all kinds of electromagnetic waves: such as
waves transmitted by radio and TV stations; waves generated from Wi-Fi equipment, computers, phones, microwave ovens, and waves from fire, radiator, and the Sun. Luckily we can only see some of them, such as, visible light, not everything, otherwise, we would become so dizzy and lightheaded that we cannot focus doing anything.
EM waves can be classified and arranged according to their different frequencies; this classification is called the EM spectrum.
My topics are organized by playlists:

This is my education channel. My topics cover networking, security, programming, data structure, algorithm, programming and other computer-related materials.

Hey Sunny. I used you in my studies for CompTIA assessments sometime ago. I'm now taking a ridiculous Physical Sciences class and found you once again. I was hesitant when I first heard you speak years ago, but I gave it a chance and you were very helpful. Thank you for your hard work to educate others. I looked for a website or donate button, but I don't see anything. So I'm gathering that you simply make these videos and upload them to KZbin for very little or no compensation/monetization. We need more people like you!

Very insightful and non biased. Technology is as good as the intentions behind the user.

[@lanceleavitt7472]

Amazing overview of the basic principles. -- *_Thanks for the great upload._*

Awesome explanation. Thank you Sunny!

[@AzzrudinJamil]

I believe that this is the most honourable and informative video i've come across. simple but effective

[@sunnyclassroom24]

Many thanks for your compliment and kindness.

Very helpful. Very clear. Thank you!!! 👏

Thank you for this video. You have opened up doors to things I always felt, but didn’t quite understand. These videos have helped tie the strings together to a lot of things that have felt undone. God bless you

Great content! That was very interesting. Thank you for this presentation!

Glad you enjoyed it!

[@JackSparrow-yt3qw]

Thanks for the interesting video. Couple of quick questions: (1) IR have three classification (near, mid and far), in order to develop IR stealth material/uniform which one of the classes shall be focused? Isn't it that if someone make far-IR stealth then it will cover both near and mid IR stealth as well? (2) Which of these three classes (Near, mid and far IR) are used by military for detecting enemies?

*Thank you so much! I will be retaking my science test and this will help a lot! However I'd appreciate it if you could talk a bit faster but it isn't really a problem because I can change the playback speed ❤︎*

[@sunnyclassroom24]

you are welcome! Sorry for the speed. I could not be able to speak faster. I will try my best. English is a challenge to me.

Oh, sorry I thought you spoke slowly so that your viewers could understand you clearly.

[@hosseinrostamzadeh]

Thanks for a very nice and instructive video. I have just a question Sunny: the colour-spectrum which shows visible light is not in "correct order", or am I wrong? While going towards shorter wavelengths the blue-violet colour must be at the right end of this little colour-spectrum, closest to UV and the red colour at the opposite end (closest to IR).

[@JOVSOnlineTV0416]

Hello Mr. Sunny, may I ask what applications you use to build your presentation? thanks

What is the highest frequency of gamma rays? What is beyond that?

[@shaunhumphreys6714]

i cant even cope with visible light and ultraviolet light. my disease caused me to become extremely light sensitive/photo phobic, i have to stay in darkness during day, and come out at sun set. i hate the sunlight, and the heat that comes from it, so that means i hate infrared too. i love darkness, winter, rain, clouds to block out the sun. i wish i couldnt see ultraviolet at all. but im sure glad i cant see any of the other electromagnetic spectrum-gamma rays would be horrible.

Awesome video, thanks so much for sharing. BTW, I need my computer (Camera, OpenCV, Arduino/Raspberry Pi) to see the shape of a head under both facial and head hair. Can you point me in the right direction please. Can a radio wave sensor capture the contour of the head/face under all the hair? If not, how about infrared, UV, heat? It would need to be pretty accurate.

[@lokeshs9931]

Hi sunny, my question is whether microwaves fall under radio frequencies category..? Or it's different from RF, till now am understanding that Radio and microwave are different category.. please explain.. thanks

[@alial-akwaa5535]

Thank you, sir, all of your videos are great and concentrated and provide the required information in a very short time. The lower spectrum has benefits, with the same amount of energy they can travel a longer distance than the higher spectrum. I've confusion and I think you can clarify and remove this confusion; in modulation video "why do we need modulation?" so the higher frequency carrier signal can travel longer distance than the lower frequency original data signal. otherwise the lower frequency requires more power/ energy to travel long distance. Here the higher frequency signal travel longer distance than the lower frequency signal, but in this "EM spectrum" video the lower spectrum travel longer distance than the higher spectrum. Could you please clarify?! Thanks in advance..

[@alial-akwaa5535]

For Modulation one benefit is the interference cancellation/ reduction. sorry my point in the previous reply is wrong about "the higher frequency carrier signal can travel longer distance than the lower frequency original data signal."

can you sleep with high frequency waves blasting? "law enforcement" bust out your wave detector....."i dont know why he did that".....Fpi.
