Question

The amount of energy carried by a wave is proportional to the square of the wave’s

A. frequency
B. amplitude
C. wavelength
D. period ...?

Answer 1

Answer: The correct answer is "amplitude".

Step-by-step explanation:

The expression of the energy in terms of frequency is as follows;

E=hf

Here, h is Planck's constant, E is the energy and f is the frequency of the wave.

Here, the energy is directly proportional to the frequency of the wave. The energy of the wave is inversely proportional to the wavelength of the wave.

Amplitude is the maximum displacement of the particle from its equilibrium position in the vertical direction.

The amount of energy carried by a wave is directly proportional to the square of the amplitude. More the energy of the wave, more will be amplitude of the wave. Lesser the energy of the wave, lesser will be the amplitude of the wave.

Therefore, the correct option is (B).

Answer 2

The amount of energy carried by a wave is proportional to the square of the wave’s amplitude. The amplitude is measured by calculating the distance from the top (or bottom) of the wave and the middle or center.
