Question

The intensity of light depends on -
1) amplitude
2) frequency
3) wavelength
4)none

Answer 1

Heya.

The intensity of light depends upon the amplitude.

Answer 2

Answer:

The intensity of light depends on the amplitude.

1 is correct.

Explanation:

Intensity :

The intensity of a light wave is explained as the amount of energy that passes through the area per unit time.

Amplitude :

Amplitude is the maximum displacement of the particles of the wave.

Therefore,

The intensity of the light directly proportional to the square of the amplitude.

$I\propto a^2$

Hence, The intensity of light depends on the amplitude.
