The most common sources of energy are the incident solar energy and the radiation from the Earth. The wavelength at which the Sun''s energy reaches its maximum coincides with the visible band range. The energy radiated from the Earth is sensed through the windows at 3 to 5μm and 8 to 14μm using devices like thermal scanners.
Electromagnetic energy travels in waves and includes various types of radiation such as light, radio waves, x-rays, and microwaves. It provides energy in forms such as electricity transmitted through power lines, visible light in different colors representing varying amounts of energy, and energy carried by technologies like X-rays, radio, and lasers.
