Question

Critical angle of a denser medium is 42 degrees. A light ray is travelled through the denser medium with an incident angle of 43 degrees . Guess the path of light ray

Answer it please​

Answer 1

Answer:

A ray of light is travelling from a denser medium to rarer medium. For these media critical angle is C. The maximum possible deviation of the ray is ___________.

A .

π−2

B .

π−2C

C .

2C

D .

π/2+C

The maximum possible deviation of the ray is the condition when total internal reflection just takes place as shown in the figure.

⇒  ∠i=∠C

So,maximum deviation is π−2C

Therefore, B is correct option.

Hope this helps you.
