Differbetween
Radio waves have wavelengths of 1 m up. The frequency at 1 m is 300 MHz. Microwaves have wavelengths of 1 mm (millimeter) to 1 m. The frequency at 1 mm is 300 GHz.

What is the difference between radio wave microwave and infrared?
THE DIFFERENCES: Microwave radiation involves a specific frequency of bands while infrared has a wider range. ... The wavelength of infrared is shorter than that of microwave radiation, which falls in between radio waves and infrared on the electromagnetic spectrum.
Are microwaves stronger than radio waves?
Microwaves have a little more energy than radio waves. Infrared has still more, followed by visible, ultraviolet, X-rays and gamma rays.
Which is faster radio waves or microwaves?
I In air, microwaves travel faster than radio waves. II In air, microwaves have a longer wavelength than radio waves. III Microwaves and radio waves are both members of the electromagnetic spectrum.
Do microwaves use radio waves?
A conventional oven heats food very slowly from the outside in, but a microwave oven uses tiny, high-powered radio waves to cook food more evenly (loosely speaking, we sometimes say it cooks from the "inside out"—although that isn't quite correct). ...
Which has more energy infrared or microwave?
The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.
Are infrared microwave radio waves harmful to us?
Electromagnetic radiation energy is produced by various electromagnetic processes. There are two types of electromagnetic radiation, visible light and invisible ones such as radio waves, infrared light and X-rays. ... This energy may potentially be damaging to us.
What are the 7 wavelengths?
The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.
What are the 7 electromagnetic waves in order?
In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves. Microwaves (like the ones used in microwave ovens) are a subsection of the radio wave segment of the EM spectrum.
What GHz do Microwaves use?
A microwave oven passes microwave radiation at a frequency near 2.45 GHz (12 cm) through food, causing dielectric heating primarily by absorption of the energy in water.
Do cell phones use radio or microwaves?
Cell Phones
Cell phone signals are carried through the air as microwaves. You can see how this works in the Figure below. A cell phone encodes the sounds of the caller's voice in microwaves by changing the frequency of the waves.
What are the dangers of radio waves?
RF radiation has lower energy than some other types of non-ionizing radiation, like visible light and infrared, but it has higher energy than extremely low-frequency (ELF) radiation. If RF radiation is absorbed by the body in large enough amounts, it can produce heat. This can lead to burns and body tissue damage.
What is the speed of radio waves in air?
Air is thin enough that in the Earth's atmosphere radio waves travel very close to the speed of light. the distance a radio wave travels in a vacuum, in one second, is 299,792,458 meters (983,571,056 ft), which is the wavelength of a 1 hertz radio signal.
