Labels:text | screenshot | font | number OCR: MICROWAVE MICROWAVES ARE a form of electromagnetic radiation - energy that can be transmitted through space in the form of waves. Microwaves have wavelengths ranging from 1 mm (0.039 in) to 300 mm (12 in) and are emitted by all types of celestial objects. At wavelengths below 3 mm (0.118 in) microwaves are strongly absorbed by the Earth's atmosphere.
