Question

The frequency of incident ray is 3x10^18Hz.The frequency after reflection
Decreases
Increases
remains the same

Answer 1

Answer:

The frequency after reflection Remains the same

Explanation:

As we know that frequency of the light ray depends upon the source only.

It only depends on the type of source and it can not change due to medium

so we will have

$f = \frac{v}{\lambda}$

so when medium changes then frequency remains the same while wavelength and speed both changes

so we will have

$\frac{v_1}{\lambda_1 } = \frac{v_2}{\lambda_2}$

so here the frequency will remain the same
