Some of the cosmic electromagnetic radiation with high frequency is blocked by the ozone layer, but it is still present in the environment. In particular, ultraviolet, x-rays, and gamma radiation are especially harmful. This is because the higher the frequency, the more energy the photons have and the more they can force the particles to change the molecular composition of tissue and other matter. The higher the frequencies (and the smaller the wavelength), the more damage the photos can inflict on the cells of living organisms. They are more active at higher frequencies. The particles that carry electromagnetic energy are called photons. Its wave component is a composite wave, consisting of the magnetic and the electric waves, which oscillate in space perpendicular to each other. Electromagnetic RadiationĮlectromagnetic radiation is the energy that has the properties of both waves and particles, known as wave-particle duality. This article mainly focuses on electromagnetic radiation and light in particular, and we will mainly consider the spectrum from UV light to infrared light. Finally, radio waves cover wavelengths of 1 meter and up.Microwave radiation follows, at 1 millimeter to 1 meter.Infrared light, also invisible to the human eye, is from 700 nanometers to 1 millimeter.The visible spectrum of color light is between 380 nm and 700 nm.Ultraviolet light, invisible to the human eye, is between 10 nm and 380 nm.Gamma rays have wavelengths up to 0.01 nanometers (nm).This cavity magnetron is used in microwave ovens to emit electromagnetic energy into the cooking chamber
