    A introduction for some basic formulas would be appreciated, like V= F x Wavelength or maybe G =10 x lg(I/(E-12) aka decibel formula, (I=P/4πr^3)

    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.

    A wave is like a signal. Waves can change direction. They can have great volume and power. In order to create a wave, a disturbance needs to be created. We can change the disturbance to motion. Now motion can be used to cause an effect that will then change an outcome. I am studying telekinesis and trying to use its functionality to acquire certain things that will benefit me. What one must realize when doing this, is that when waves bounce back off a particle, it can cause a reverse reaction.

    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 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.

    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.

    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.
