Answer:
ANSWER
ANSWERIf the angle of incidence and angle of emergence of a light ray falling on a glass slab are given then by applying snell’s law we can
2
sinrsini = n 1 n 2
When the light travels from the air to glasssinrsini =μ ga Now the light travels withing the glass the angle of incidence is equal to the angle of reflection
When light goes out of the glass into air then according to snells lawsinesinr = n 2 n 1 sinesinr =μ ag On multiplying the above two equation we getsinesini =1sini=sinei=rHence the angle of incidence is equal to the angle of emergence and the rays are parallel to each other.
Explanation:
Is the emergent ray from glass slab parallel to the incident ray ... yes . It is parallel to incident ray. when light ray is enter in glass slab,it gets bend due to refraction of light. Refracted ray also try to escape out from slab so it fall on another side of slab and refract ,then emergent ray is came in manner with parallel to incident ray.
