Question

The intensity of the refracted light is always __________ than the intensity of the incident light​

Answer 1

Answer:

The intensity ( or the amplitude) of refracted light will obviously be less than that of the incident light because a part of light is reflected.

Answer 2

The intensity of the refracted light is always less than the intensity of the incident light​.

• When a ray of light travels from one medium to another, a major part of it is refracted. However, some part of it is reflected back in the previous medium itself.
• Thus, we can conclude that the refracted light will always have less intensity as compared to incident light.
• The intensity of refracted light also depends upon the angle of incidence. As the angle of incidence is increased, the angle of reflectance is increased too and more intensity of light will be reflected.
• As a result, the intensity of refracted ray will decrease.
