Microwaves are high frequency radio waves. They were discovered by an engineer working on high frequency transmission and noticed his coffee got warm near the transmitter.
They burn internally because of their energy levels and frequency. That makes then more dangerous then lower frequencies.
'Microwaves' ARE radio waves, and they're not necessarily any more dangerous
than any other radio wave with any other wavelength or frequency. The danger
only arises when you think about where you're likely to come in contact with
different kinds of radio waves, and how much.
-- Radio waves from AM, FM, TV stations:
They start out with hundreds or thousands of watts of power, from the tops of
tall towers. By the time they reach you, they're all spread out, and you're hundreds
of feet down and several miles away.
-- Radio waves from cellular telephone and mobile data repeaters:
They start out with 20 or 30 or 50 watts of power, from the tops of short towers.
By the time they reach you, they're all spread out, and you're way down on the
ground and a few miles away.
-- Radio waves from GPS satellites and TV satellites:
They start out with 50 or 100 watts of power, from 22,000 miles out in space.
-- Radio waves from the cellphone you talk on:
They start out with 1/2 watt or 1 watt or 2 watts of power. What's that you're doing . . .
holding it up next to your eyes and your brain ? ! ? A lot of people aren't too sure
about that yet.
-- Micro-radio-waves used to beam telephone conversations and stock trades
along intercity routes where fiber is too expensive and satellite links are too slow:
They start out with 1/4 watt or 1/2 watt from the top of a tall tower, and they
use big dish antennas to focus the power straight out in front of them. By the
time they reach you, you're hundreds of feet below, miles away, and if you have
another big dish antenna handy to collect them with, you might be able to collect
as much as 0.00001 watt of power.
-- Micro-radio waves used to heat meatloaf and make popcorn in a box on the counter
in your kitchen:
They start out 600 watts or 1,200 watts, or 2,000 watts of power, and you
stand there a few feet away waiting for the corn to pop, and the only thing
standing between you and enough radio-wave power to cook meat is that
thin RF filter in the window of the box.
You get less radiation exposure climbing a tower with ten microwave dishes and an FM transmitter on it than you get when you warm up the leftover meatloaf in the microwave oven.

What is the difference between infrared waves and microwaves?
Microwaves are electromagnetic waves that occur on the EMR (Electromagnetic Radiation) scale above radio/tv waves and below infrared and visible light waves. They are used in cooking devices (microwave oven) and as carrier waves for cell phone and other communication devices. In other words, a "microwave" is a type of electromagnetic radiation (like visible light waves, tv waves and so on), and a "microwave oven" is a cooking device that uses microwaves to heat foods by stimulation of the water molecule.

Which one is higher energy gamma waves ultra violet waves microwaves radio waves?
The smaller the wavelength (high frequency), the higher the energy. So gamma has the highest energy, followed by x-rays, UV, visible, infrared, microwaves, radio, in descending order. This is also why green laser-pointers are more expensive than red ones ;)
Do radio waves disturb matter?
Radio waves will disturb matter which is more or less on the order of magnitude of the wavelength of the waves.
Does your body emit radio waves?
Our eyes cannot sense radio waves. Although radio waves, visible light waves, X-rays and gamme rays are all part of the Electromagnetic Spectrum, our eyes are only equipped to detect the part of the spectrum known as visible light.
What travels faster radio waves or ultraviolet waves?
neither... they both are electromagnetic waves and therefore travel at the same speed... but ultraviolet waves have a higher frequency and also have more energy than radio waves
Do microwaves have more or less energy than radio waves?
Microwaves have more energy than radio waves. They have shorter wavelengths and higher frequencies, which results in more energy being carried by microwaves compared to radio waves.
Which is more dangerous Visible waves or microwaves?
Microwaves are generally more dangerous than visible waves because they have higher energy levels that can penetrate deeper into tissues and cause harm. Visible waves, such as light, have lower energy levels and are less likely to cause harm to the body.
Which type of electromagnetic wave has a wavelenght longer than that of microwaves?
Radio waves have a longer wavelength than microwaves.
How are both radio waves and microwaves used for communication?
Radio waves and microwaves are both used for communication through technologies such as mobile phones, Wi-Fi routers, and satellites. Radio waves are commonly used for long-range communication, while microwaves are more often used for shorter-range communication and can carry higher data rates. Both types of waves are able to transmit information wirelessly by modulating their characteristics to encode data.
Do radio waves have more energy then microwaves?
No, radio waves typically have lower energy than microwaves. Radio waves have longer wavelengths and lower frequencies, while microwaves have shorter wavelengths and higher frequencies, resulting in higher energy levels for microwaves.
What are infa-red waves used for?
Infrared waves are special waves that helps you get rid of wrinkles.

Would microwaves have a high or low penetrating ability relative to other em waves?
Microwaves have a moderate penetrating ability compared to other EM waves. They can penetrate materials like food and some plastics, but can be absorbed by metals and water. This property makes them useful for cooking and telecommunications.
What radiation that travels as waves?
The radiation that travels as waves includes electromagnetic radiation, such as visible light, radio waves, microwaves, and X-rays. These waves vary in frequency and energy, with higher frequencies corresponding to more energetic radiation.
Name four tpes of electromagetic wave?
radio waves, microwaves, visible light, x-rays Check out EM spectrum for more info
How are microwaves different from radio waves?
"Microwave" is the loose term used to describe the higher-frequency portion of the general category of radio waves. The closest thing to a formal definition says that "microwave" is anything with a frequency higher than 3 GHz (wavelength less than 10 centimeters).
What kind of electromagnetic wave has a wavelength of 1Cm?
A wavelength of 1 cm corresponds to microwave electromagnetic waves. These waves are commonly used in technologies such as radar, wireless communications, and microwave ovens.
