Question

A ray of light incident on a transparent block at an angle of incidence 60°

If u of block is
of block is √3 then angle of deviation of refracted rays is...​

Answer 1

Answer:

Explanation:

Using Snell's law:

⇒sin i/sin r,

⇒v1/ v2,

⇒μ1/μ2,

⇒μ2sin r/μ1 sin i,

The value of √3 is 1.732,

⇒1.732×sinr=1×sin60',

⇒sin r=1/2,

⇒r=30°

 

⇒so,angle of deviation=60°−30°

 

= 30°
