With the help of suitable example, explain how science is applied.

Why does a matchstick light when we strike it on a rough surface ?

A vertical ray of light strikes the horizontal surface of some water: a) What is the angle of incidence? b) What is the angle of refraction?

A beam of light strikes a surface at angle of incidence of 60^(@) and reflected beam becomes completely polarised . The refractive index of glass surface is -
