WebThe range of visible wavelengths is 400 to 700 nanometers. Ultraviolet light is the radiation from the sun that causes a sunburn when you have been outside too long on a sunny day. But, watch out! You can't see ultra-violet light, so you can still get sunburned on a cloudy day. The range for ultraviolet light is 10-8 to 10-10 meters.
WebNov 28, 2024 · Why does AM have longer range than FM? AM broadcasts use longer wavelength radio waves than FM broadcasts. Because of their longer wavelengths, AM waves reflect off a layer of the upper atmosphere called the ionosphere. However, the relatively short wavelengths of FM waves means that they don’t reflect off the … WebApr 10, 2024 · Radio waves are a kind of electromagnetic wave whose wavelength falls in the electromagnetic spectrum.
