Answer:
option A
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
[tex]\mu = \dfrac{sin i}{sin r}[/tex]
[tex]\mu = \dfrac{sin 55^0}{sin 37^0}[/tex]
[tex]\mu = 1.36 [/tex]
The refractive index of the material is [tex]\mu = 1.36 [/tex]
hence, the correct answer is option A
