Question

If light is incident on a plane surface at 55 deg traveling from air, and is refracted through an angle of 37 deg, what is the index of refraction of the material? A. 0.73

B. 47
C. 1.36

Answer 1

option A

Step-by-step explanation:

given,

light is incident on the plane surface at (i) = 55°

angle of refraction (r) = 37°

μ is the refractive index of the material

using Snell's law

`\mu = (sin i)/(sin r)`

`\mu = (sin 55^0)/(sin 37^0)`

`\mu = 1.36`

The refractive index of the material is
`\mu = 1.36`

hence, the correct answer is option A
