The very lowest energy range of UV between 315 nm and visible light (called UV-A) is not blocked well by the atmosphere, but does not cause sunburn and does less biological damage. However, it is not harmless and does create oxygen radicals, mutations and skin damage. Visa mer The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies. The electromagnetic … Visa mer Electromagnetic waves are typically described by any of the following three physical properties: the frequency f, wavelength Visa mer Radio waves Radio waves are emitted and received by antennas, which consist of conductors such as metal rod resonators.

Webb7 dec. 2024 · The order of energy from least to greatest is: microwaves, infrared, red, ultraviolet, and gamma waves. The energy of an electromagnetic wave is directly proportional to its frequency. This means that the greater the frequency, the greater the energy. The amount of energy a wave has is determined by using the formula: E=hnu, … WebbThe entire electromagnetic spectrum, from the lowest to the highest frequency (longest to shortest wavelength), includes all radio waves (e.g., commercial radio and television, microwaves, radar ), infrared radiation, … greatest source of thermal pollution
