Question

A thin prism of refracting angle 2° and of refractive index 1.5, deviates an incident ray through a given angle. What is the angle of deviation?

Answer 1

here you go. for thin prism angle of deviation is this so from this formula it comes out to be 1°..

give me brainly..

Answer 2

Given that,

Refractive index, n = 1.5

Angle of prism, A = 2 degree

To find,

The angle of deviation.

Solution,

The relation between angle of deviation, angle of prism and the refractive index is given by :

$\delta=(\mu -1) A\\\\\delta=(1.5 -1) \times 2\\\\\delta =1^{\circ}$

So, the angle of deviation is 1 degree.
