Question

Find the refractive index of the material if angle of incidence is 45 degree and angle of refraction in the material is 30 degree

Answer 1

Answer:

Explanation:

Using Snell's Law,

sin i/sin r

= sin 45/sin 30

= 1/ root 2 * 2

= root 2

= 1.41 is the refractive index

Answer 2

The refractive index of the material is 1.41.

Explanation:

Given that,

Angle of incidence, i = 45 degrees

Angle of refraction, r = 30 degrees

It is required to find the refractive index of the material. It can given by using Snell's law as:

$n=\dfrac{\sin i}{\sin r}\\\\n=\dfrac{\sin (45)}{\sin (30)}\\\\n=1.41$

So, the refractive index of the material is 1.41.
