If the amplitude of a wave increases by a factor of 4, how is the intensity changed? it increases by a factor of 4 it increases by a factor of 16 it decreases by a factor of 4 it decreases by a factor of 16.

Sagot :

If the amplitude of the wave increases by 4 times, the intensity will increase by 16 times. Option B is correct.

What is the relation between the intensity and the Amplitude?

The intensity is directly proportional to the square of the amplitude of the wave.

[tex]I \propto A^2[/tex]

[tex]I = k \times A^2[/tex]

Where,

[tex]I[/tex]- Intensity

[tex]A[/tex] - Amplitude

[tex]k[/tex] - constant

Thus, if the amplitude of the wave increased by 4 times,

[tex]I = k \times(4A)^2\\\\I = k \times 16A^2[/tex]

Therefore, if the amplitude of the wave increases by 4 times, the intensity will increase by 16 times.
