Question

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

Answer 1

3. #3 is wrong. The medium DOES move, back and forth.

The others are OK

Answer 2

#3is correct!!!!!!!!!! becuz in wave motion,it transfer WAVE ENERGY only without transferring the matter.Bear in mind!
