Question

When a Ray of light is passing through a glass slab the correct value of angle of incidence angle of refraction and angle of emergence are respectively *

40, 30, 30

30, 40, 30

40, 30, 40

40, 40 ,40

​

Answer 1

Hence, angle of incidence should be taken between 30° and 60° for tracing the path of ray of light through a glass slab

Answer 2

Answer:

40 , 30 , 30

Explanation:

i am not sure but i think this is the answer
