Wavelength

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

Electromagnetic Radiation

Energy that travels through space in the form of waves, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Vibrational Motions
