Question

Sorry if i picked the wrong subject

Answer 1

Answer:

D

Explanation:

speed is constant in a certain medium.

phase is not directly related to the energy.

intensity and wavelength both determin amount of energy carried by the wave. however, in this question in first examples wavelength is pointed out. I guess D is the correct answer.

For B and D:

$energy = \sqrt{ \frac{2 \times i}{c \times \: epsilon } } \: \: \: \\ energy = \frac{hc}{lambda}$

the first one is relation between intensity (i) and energy.

the second one is the relation between wavelength (lambda) and energy.
