Question

A parallel beam of light λ=5890Å, is incident on a glass plate (µ=1.5) such that angle of refraction into plate is 60⁰. Calculate the smallest thickness of the plate which will make it appear dark by reflection.

Answer 1

Convection is the heat transfer due to bulk movement of molecules within fluids such as gases and liquids, including molten rock. Convection takes place through advection, diffusion or both.
