The highest-energy waves on the spectrum, gamma rays are produced by radioactive decay and cosmic events like supernovae. Cancer treatment (radiotherapy) and sterilizing food.
Because they are ionizing radiation, doctors use lead aprons to protect vital organs during X-ray procedures. 7. Gamma Rays
Remote controls, thermal imaging cameras, and fiber optic cables. electromagnetic spectrum
Visible light is actually a tiny fraction of the total electromagnetic spectrum. 5. Ultraviolet (UV)
Gamma rays can pass through several inches of lead or a few feet of concrete. Atmospheric Windows The highest-energy waves on the spectrum, gamma rays
Because the speed of light is constant, wavelength and frequency are inversely proportional: as the wavelength gets shorter, the frequency (and the energy of the photon) increases. Regions of the Spectrum
Microwave ovens, satellite communication, and radar systems. Regions of the Spectrum Microwave ovens
Microwaves range from about 30 centimeters to 1 millimeter in wavelength.
