PS4A - Wave Properties

[@natefanning9709]

Hi Paul, I want to point out a small correction you could make. At 1:45 you stated that a "low-density gas" would allow your voice to produce a low frequency wave, making a lower pitched sound. That is incorrect, as helium is an example of a low density gas, and is what allows our voice to make a higher pitched sound since it is unable to slow down the vibrations from our voice like air does. A high density gas, or medium, produces a lower frequency and lower pitched sound. Using sulfur hexaflouride instead of helium would work well to get a really low pitched sound!

Thank you for putting this together! I appreciate the connections to the importance of waves for middle school students.

Mr. Andersen, you deserve more views & subscribers !! I've been watching you for about three months, your videos are great. I'll do my best to spread your channel.

[@lostaspects13]

Pedro Fischer I dissagree

Thank you for your hard work. I can't believe that only a few people are interested in these things, I feel like the next generations is going to fall real bad.

6:50 if the wave pulse in opposite direction have cancelled each other out when they meet how are they produced again?

[@Racegas]

You probably already figured this out considering its been 3 years but I can still explain it if you wish

[@maheswaran3331]

How the waves are generated in electric circuit?

[@Jarrod_C]

How do you explain a surfer on a wave that is traveling forward because of the wave? Why do Tsunamis carry water onshore? I have a hard time visualizing how waves do not move the medium in the direction of the propagating sound or light.

[@Luahm5]

As far as im imagining the surfer isnt the meduiem. The water is, and the water isnt being transefered from a place to another but u can think of it as if the energy is being pushed, and when its transferring from a place to another it causes disturbance. Imagine for eg a blanket (the meduim) and a ball under it (the energy), when u move the ball while its under the blanket from a place to another it causes disturbance to the blanket but it doesnt move it from a place to another. Idk if this is helpful but it is working for me. Good luck.

You need to get into PDE (Pulse Detonating Engines) or Pulse Jet Engines.I just want to fully know how my RC PJ engine works so I can design a better one.Waves have so many New uses still to be invented.

I hope Grammarly goes out of business as soon as possible.

[@tahadaboussi7831]

hi i want to ask you some thing what is medium ?

[@conorkenney3523]

Taha Daboussi it is what occupies the space where the wave is travelling. ie. air, water, or a solid
