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
