Millimetre waves are Extremely High Frequency (EHF) electromagnetic waves with wavelengths in the millimetre range.
EHF frequencies are from 30 GHz (30 000 MHz) to 300 GHz (300 000 MHz), and EHF is considered the highest radio frequency band - above this, electromagnetic radiation is considered to be infra-red.

What type of energy is used with full body scanners in the aiport?
Those are "millimeter waves" ... radio waves in the general neighborhood of 300 GHz.
Can different electromagnetic waves be converted to a single frquency?
We have the technology to do that, but only with waves longerthan about 1 millimeter (frequencies below 300 GHz).

Are millimeter-waves a form of x-ray?
They're the exact same physical phenomenon ... electromagnetic radiation ... but x-rays have much shorter wavelengths. X-rays are the name we give to those waves in the range of 0.01 to 10 nanometers. That's 0.00000001 to 0.00001 millimeter.
Why do astronomers observe the galaxy at millimeter wavelength?
Millimeter wavelengths are short frequency radio waves astronomers use because they can see gases and other phenomena not visible in visible light. MM wavelengths are usually used where the air is dry so water vapor can't scatter the waves.

What kind of waves have wavelengths of about 1-200 meters?
We would call any wave longer than 1 millimeter a "radio wave".
What size wavelengths do harmful types of electromagnetic waves have?
very small wavelengths (near-infrared, far-infrared, sub-millimeter, microwaves)
How are millimeter waves used in everyday life?
They are used in telecommunications for high-speed wireless broadband communication and point-to-point wireless local area networks (WLANs).
What is the metric unit for 1 millimeter?
A millimeter is a unit of length.
