Planck's relation

Electrons can only gain and lose energy by jumping from one allowed orbit to another, absorbing or emitting electromagnetic radiation with a frequency ... more

Radiation Pressure by Reflection (using particle model: photons)

Radiation pressure is the pressure exerted upon any surface exposed to electromagnetic radiation. Radiation pressure implies an interaction between ... more

Relative velocities (general case)

The relative velocity (v_A|B) is the velocity of an object or observer B in the rest frame of another object or observer A.

The general formula ... more

Relative velocities (parallel direction)

The relative velocity (v_A|B) is the velocity of an object or observer B in the rest frame of another object or observer A.
