Basic Physics and Chemistry Concepts

Front

The distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.

Back

Wave length

Front

The formula to calculate wave length is λ = v/f, where λ is the wavelength, v is the velocity of the wave, and f is the frequency.

Back

Wave length formula

Front

The range of all types of electromagnetic radiation.

Back

Electromagnetic spectrum

Front

Energy that is propagated through free space or through a material medium in the form of electromagnetic waves.

Back

Electromagnetic radiation

Front

A fundamental constant, h, which is the quantum of electromagnetic action that relates a photon's energy to its frequency.

Back

Plank's constant

Front

The heat change that occurs at constant pressure when a chemical reaction or physical change occurs.

Back

Enthalpy change

Front

A process or reaction that absorbs energy in the form of heat.

Back

Endothermic

Front

A process or reaction that releases energy in the form of heat.

Back

Exothermic

Front

Energy cannot be created or destroyed, only transformed from one form to another.

Back

Law of conservation of energy

Front

Energy cannot be created or destroyed in an isolated system.

Back

1st law of thermodynamics
