Answer:
The length of the rope must be an integral multiple of the wavelength of the wave.
Explanation:
First do 1.6 m (how far he jumps) 9.8 m/s (what gravity is measured at) then times 2
= 31.36
Sq root = 5.6
6 . . . . . a crest
7 . . . . . the amplitude
8 . . . . . the wavelength
9 . . . . . a trough
Answer:
It refracts when it hits the glass.
