Because they don't have enough energy (or a short enough wavelength) to knock electrons off of atoms (ionization).

Which travels faster radio waves or microwaves?
-- Microwave ARE radio waves.-- All electromagnetic waves travel at the same speed, including radio, microwaves,heat, infrared radiation, light, ultraviolet radiation, X-rays, gamma rays, and allthe others.
What is the radiation source for microwaves waves?
Microwave frequency radio waves are usually produced by a MAGNETRON.
What electromagnetic wave has a wavelength greater than that of light?
Radio, microwaves, radar, and infrared radiation have.
Which of the following is not a form of radiation A Radio waves B Sound waves C Microwaves D Gamma waves?
Sound waves
Which light has a lower frequency than an infra-red radiation?
Microwaves and radio waves.
Are microwaves a type of radio wave?
Microwaves are a frequency of electromagnetic radiation. It has a higher frequency than radio waves, but has a lower frequency than infrared light.
What type of waves are electromagnet waves?
electromagnetic waves
Type of radio waves that excites water molecules?
Radio waves are a form of electromagnetic radiation. The EM waves used in microwaves are chosen speciiffically for there ability to excite water molecules.
Is radio waves a form of radiation?
Yes, radio waves are electromagnetic waves.They are in the part of the spectrum with the longer wavelengths, longer than microwaves, and visible light waves.
What are the categories of the electromagnetic spectrum?
Long waves, medium waves, Short waves coming under Radio waves. Microwaves Infra red Visible light Ultra violet X-radiation Gamma radiation
What has a wavelength longer than visible light?
Assuming you mean other electromagnetic waves: that would be infrared radiation, microwaves, and radio waves.
Would microwaves have a high or low penetrating ability relative to other em waves?
microwaves are more penetrative than gamma rays, UV radiation and visible light, but less so than radio waves.
