3. #3 is wrong. The medium DOES move, back and forth.
The others are OK
I had a couple of questions on the topic of Waves-Sound and Light.
1. What is the source of all waves?
*Vibration*
2. In one word, what is it that moves from source to receiver in a wave motion?
*Energy*
3. Does the medium in which a wave travels move with the wave?
*No*
4. What is the relationship among frequency, wavelength and wave speed?
*wave speed=wavelength * frequency
