What is refraction of light?

What is refraction of light?

Write the formula for refraction at a thin lens.

State Snell's law of refraction of light.

Prove the following formula when refraction takes place at a convex spherical refracting surface and source of light lies in the rarer medium and image formed is real frac(mu_2)(v)-frac(mu_1)(u)=frac(mu_2-mu_1)(R) Where the terms have their usual meanings.
