Rays

Radiowaves• Longest wavelengths• Lowest frequencies• Used in broadcasting

Microwaves• Radiowaves with the shortest wavelengths and highest frequencies• Ex: radar guns

Infrared Rays• Wavelengths are shorter than radiowaves• Ex: heat lamps and infrared cameras

Visible Light• Can see• White light can be separated into red, orange, yellow, green, blue, and violet

Ultraviolet Rays• Energy is great enough to damage or kill living cells

X-rays• Can penetrate most matter• Too much exposure can cause cancer

Gamma Rays• Shortest wavelengths• Highest frequencies• Most penetrating of all waves
