Question

5. A ray of light is incident through glass, with refracht
index 1.52, on an interface separating glass and we
with refractive index 1.32. What is the angled
refraction if the angle of incidence of the ray in glass
25°?

Answer 1

Answer:

Thus the value of angle of refraction is 29.1°

Explanation:

We are given data:

Refractive index of glass = 1.52

Refractive index of water = 1.32

Angle of incidence "i" = 25°

To find: Angle of refraction "r" = ?

Solution:

Using Snell's law:

n1 ( Glass) = 1.52

n2 (Water) = 1.32

n1 sin (i) = n2 sin t

1.52 sin (25°) = 1.32 sin r

r =  [arc sin (1.52 / 1.32) sin 25° ]

r = 29.1°

Thus the value of angle of refraction is 29.1°
