A mechanical wave requires a medium. For an ocean wave this medium would be
Question 4
4.
The medium for a sound wave would be
Question 5
5.
All mechanical waves have amplitude, wavelength, period, and wave speed. Look in the area between the arrow to the word elevation and the aline showing amplitude. How many cycles of the wave is show here?
Question 6
6.
Frequency is the number of full cycles (crest to crest) a wave passes in a second. The unit, a hz, can be converted to what SI unit?
Question 7

Question 10
10.
Define white light
Question 11
11.
Of the following, which carries the most energy?
Question 12
12.
you were given two equations ---> E = hc/ʎ and c= ʎv
In both these equations ʎ stands for
Question 13
13.
because c is constant for the speed of light, wavelength and frequency are considered
