Energy & Waves

The Electromagnetic Spectrum is the entire range of all types of electromagnetic radiation. Scientists use radio waves for communication, infrared waves for thermal imaging, visible light for sight, and x-rays and gamma rays for medical imaging and treatment.

Amplitude is a wave's maximum displacement from its resting position. 

Frequency is the number of complete cycles of a wave that pass a fixed point per unit of time. 

A wavelength is the distance between two crests (tops) of two waves.

Radio waves have the longest wavelengths while Gamma rays have the shortest wavelengths.

The shorter the wavelength is, the higher the frequency is and the higher the energy is.

Radio waves have the least energy while Gamma rays have the most energy.
