Answer 2

Explanation:

1. When a ray of light approaches a smooth polished surface and the light ray bounces back, it is called the reflection of light

2. If 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 get,

sinrsini=n1n2

sinesinr=n2n1

On multiplying the above two equation we get

sinesini=1

sini=sine

Hence the angle of incidence is equal to the angle of emergence
