Gamma Rays are very deadly and their uses are limited. They are used for gamma spectroscopy.
X-rays are used for detection of composition of various substances and for viewing the structure of the bones.
Ultraviolet rays are used for sterilization.
Visible light, well you know all about it.
Infrared rays are used for low light Photography.
Microwaves are used for heating substances.
Radiowaves are used for communications.
It uses radio waves between the range of 2.402 and 2.480 GHz
no
Sonar navigation uses sound waves; radar navigation uses electromagnetic waves (usually radio eaves).
The radio frequency portion of the electromagnetic spectrum uses radio telescopes.
The radio frequency portion of the electromagnetic spectrum uses radio telescopes.
Digital Versatile Disc (DVD) uses 650nm wavelength laser diode light (part of the electromagnetic spectrum, in visable light section) which allows us to see it. CD uses 780nm wavelength, just outside of the electromagnetic spectrum, hence why we cannot 'see' it, only hear.
electromagnetic radiation in the microwave range some times cell phones use 50% uses and 50%health prombles overtimes don t uses
Actually, there's only one. Even though we like to give different labels to electromagnetic waves with different wavelengths according to their uses or effects, they're all the same physical phenomenon.
The ones we call "radio waves". That's the electromagnetic spectrum between maybe roughly speaking 10 KHz to 300 GHz., or wavelengths between 1 mm to 30 km.
WiFi uses electromagnetic waves in the microwave band, around 2.4 GHz or 5 GHz.
Radar uses radio waves.
we use electromagnetic waves in radios and cell phones
