Radio Waves - An electromagnetic wave of frequency, used for long distance communication. You most likely know it for warming your food. Microwave - In communication, it is used in radar. They are released by heat or thermal energy. IR - Infrared rays - Heat waves given off by thermal bodies. Now to the right of the visible spectrum. Visible spectrum - The visible spectrum of light is the section of the electromagnetic spectrum that is visible to the human eye. Light with a wavelength immediately shorter than any light in the visible spectrum is called Ultraviolet Light. UV (ultraviolet rays) - is an electromagnetic radiation with a wavelength from 10 nm to 400 nm, shorter than that of visible light but longer than X-rays. Most X-Rays have a wavelength ranging from. X-Rays - also a wave of high energy and short wavelength. Gamma Rays - the highest in frequency and energy, are the most damaging. You'll find Gamma rays, X-Rays and Ultraviolet rays categorized here. These types of radiation are harmful to living organisms, due to their extremely high frequencies. If you look at the l eft of the visible spectrum. Visible light represents a small fraction of the entire EM spectrum. The image below details the electromagnetic spectrum with light highlighted. Light is energy that will take on different forms. This classification determines if the electromagnetic radiation sits to the left or right of the Visible spectrum. Visible light is usually defined as having wavelengths in the range of 400–700 nanometers (nm) or one billionth of a meter.ĮM waves are categorized according to their wavelengths and frequencies (number of waves passing a point in a certain time). It is usually characterized by the Greek symbol λ. Light is measured by its wavelength (in nanometers). What are Wavelengths?Ī wavelength is the horizontal distance between the two peaks of the wave. Because of this attribute, light can be defined by its wavelength. One of lights characteristics is how it behaves like a wave with its peaks and valleys, or crest (highest point) and trough (lowest point). The EM spectrum of light includes a range of light waves.
