Question

what is the reflection and refraction of light with their laws

Answer 1

The law of reflection states that, on reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray. (By convention, all angles in geometrical optics are measured with respect to the normal to the surface—that is, to a line perpendicular to the surface.)

Answer 2

refraction .and reflection both the incident showed by lights
refraction .. when light when to 1m into another medium then the light used to bend to there actual way .. that called refraction. ..
law. .
sini/ sinr=refractive index


reflection. . in which light replect by any thing and retrace same medium is called reflection.
law
angle of reflection =angle of incidence .


I tried to make simple language. so I hope u will get

mark it brilliant
