Brewster's law

Physics; General physics

States that the refractive index of a material is equal to the tangent of the polarising angle for the material.

Graham's law of diffusion

Physics; General physics

The rate of diffusion of a gas is inversely proportional to the square root of its density.

Joule's law of heating

Physics; General physics

The heat produced when a current 'I' flows through a resistor 'R' for a given time't' is given by Q =I2Rt.

Kelvin's statement of second law of thermodynamics

Physics; General physics

It is impossible that, at the end of a cycle of changes, heat has been extracted from a reservoir and an equal amount of work has been produced without producing some other effect.

Kepler's first law of planetary motion

Physics; General physics

Each planet moves in an elliptical orbit, with the sun located at one of the foci.

Kepler's second law of planetary motion

Physics; General physics

The radius vector joining the planet to the sun covers equal areas in equal intervals of time.

Kepler's third law of planetary motion

Physics; General physics

The square of the period of a planet is directly proportional to the cube of the radius of the semi major axis of the orbit.
