Question

State the laws of refraction in light

Answer 1

If a ray passes through the focus it passes through principal axis after refraction

If a ray passes through the principal axis it passes through the focus after refraction

If a ray passes through the optic centre of the lens it gets undeviated

Answer 2

Answer:

• The normal , incident Ray and refrected Ray lie at same plane.

• [ Sini / sinr = constant ]

• The ratio of sin of angle of incident with sin of angle of refraction is constant
