Question

30. A monochromatic ray of light strikes the surface of transparent medium at an angle
of incidence 60° and gets refracted into the medium at an angle of refraction 45º.
What is the refractive index of the medium ?​

Answer 1

Answer:

Mark it As BRAINLEST

Explanation:

By Snell's law

$\frac{sini}{sinr}$

therefore

$\frac{sin60}{sin45}$

Solving it we get,

-0.3582199 it is the answer.

Answer 2

Answer:

1.22

Explanation:

i=60°

r=45°

n=sini/sinr

  =sin60°/sin45°

  =√3/2/1/√2

  =√3/√2

  =√1.5

  =1.2247448714

  =1.22
