Question

Mathematically speaking, the energy of a wave is directionally proportional to the square of the amplitude of the wave Calculate the energy of a wave that has an amplitude of 4 units A)1.0 B)2.0 C)4.0 D)160

Answer 1

The energy of the wave is D) 16.0 units squared

Explanation:

The energy of a wave is directly proportional to the square of the amplitude of the wave.

Mathematically, this can be written as

$E\propto A^2$

where

E is the energy of the wave

A is its amplitude

For the wave in this problem, the amplitude is

A = 4 units

Therefore, assuming that the constant of proportionality is 1, the energy of this wave is

$E=A^2=4^2=16$ units squared
