It uses radio waves between the range of 2.402 and 2.480 GHz
Visible light

Visible light, which lets humans and other animals see, is part of the electromagnetic spectrum. RF (radio frequency) waves are part of the electromagnetic spectrum. RF transmissions carry radio and television broadcasts. They have the lowest frequency. Microwaves are part of the electromagnetic spectrum. X-Rays are part of the electromagnetic spectrum and have the highest frequency..
The radio frequency portion of the electromagnetic spectrum uses radio telescopes.
The ozone layer protects us from UV's. UV's are a part of sun's electromagnetic spectrum.
Light at 489 nanometers is in the blue area of the spectrum. Use the link below for more information.
We can get information from any portion of the electromagnetic spectrum provided we use the correct "listening" devices; that is the entire range, Radio, microwave, infrared, visible, ultra violet, xray, and gamma rays
mobile phones use microwave radiation
Because we can't see the colors on the spectrum so we have to use a graphto show the colors.
Quite simply, the Microwave Oven uses the Microwave part of the spectrum.
The electromagnetic spectrum spans from the lowly radio signals (1x104 Hz) that we use for terrestrial broadcasting to gamma rays (1x1021 Hz) from the sun! ===================
Chloroplasts of different plants absorb different wavelengths, but usually regions within the Visible light band are used.
