Free Games & Activities
In electromagnetic radiation infrared means having a wavelength just greater than that of the red end of the visible light spectrum but less than that of microwaves. Infrared radiation has a wavelength from about 800nm to 1mm and is committed particularly by heated objects.
Electromagnetic Waves are created as a result of vibrations between an electric field and a magnetic field.
The Electromagnetic spectrum is the range of frequencies of electromagnetic radiation and their respective wavelengths and photon energies. The electromagnetic spectrum covers electromagnetic waves with a wide range of frequencies. This frequency range is divided into separate bands called by different names beginning at the low-frequency or long wavelength that include radio waves and microwaves. At the high-frequency or short wavelength and there are x-rays and gamma rays.
