EM waves

EM waves:

R MIV UXG

Wavelengths - 

Radio: 1m - 10^4m

Microwaves: 10^-2m

Infrared: 10^-5m

Visible: 10^-7m

Ultraviolet: 10^-8m

X-rays: 10^-10

Gamma: 10^-15

All EM waves travel at the same speed through air/vacuum so this means shorter wavelengths have higher frequencies. Higher frequency wavelengths transfer more energy so gamma, ultraviolet and X-rays can be dangerous as they are ionising (they…
