I had a couple of questions on the topic of Waves-Sound and Light.
1. What is the source of all waves?
2. In one word, what is it that moves from source to receiver in a wave motion?
3. Does the medium in which a wave travels move with the wave?
4. What is the relationship among frequency, wavelength and wave speed?
*wave speed=wavelength * frequency
This question looks familiar. Didn't I answer it already? #3 is wrong.
By the way, with light, there is no "medium". Light will go through a vacuum.
