Question: Refraction of light from air to glass and from air to water are shown in figure (i) and figure (ii) ...

Refraction of light from air to glass and from air to water are shown in figure (i) and figure (ii) below. The value of the angle in the case of refraction as shown in figure (iii) will be (i) figure (ii) figure (iii) figure:

(i) (ii)

(iii)

A

30∘30 ^ { \circ }

B

35∘35 ^ { \circ }

C

D

41o

Answer

35∘35 ^ { \circ }

Explanation

Solution

: aμg=sin⁡60∘sin⁡35∘{ } ^ { a } \mu _ { g } = \frac { \sin 60 ^ { \circ } } { \sin 35 ^ { \circ } } …(i)

…(ii)

…(iii)

sin⁡θ=sin⁡35∘\sin \theta = \sin 35 ^ { \circ }

θ=35∘\theta = 35 ^ { \circ }
