Question

A ray of light impinges on a transparent material at some angle with the normal. If the material has a higher index of refraction, as it enters, the ray will ______________. A ray of light impinges on a transparent material at some angle with the normal. If the material has a higher index of refraction, as it enters, the ray will ______________. bend to make a larger angle with the normal continue going in the same direction bend to make a smaller angle with the normal

Answer 1

Answer:Explained below

Step-by-step explanation:

(a) The ray of light will be bend more towards the normal because refractive index of material is more than the incoming medium .This can be explained by snell's law.

`\theta`is incident angle and
`\phi`is refractive angle

`n_1sin\theta =n_2Sin\phi`

as
`(n_1)/(n_2)sin\theta =sin\phi`

as
`(n_1)/(n_2)` is less than 1 therefore \phi is less than \theta
