The diagram shows a wave. the quantity shown is the amplitude. this quantity is directly proportional to which of these other quantities? a) energy b) frequency c) period d) wavelength

As we know that frequency and wavelength are dependent on each other

and this is given by

here we know that

= wavelength

f = frequency

c = speed of wave

while for energy and intensity of wave we know that

Energy =

here A = amplitude of wave

so energy directly depends on amplitude of wave

so correct answer will be

A)Energy

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).
