The wavelengths of visible light are: Violet: 380–450 nm (688–789 THz frequency) Blue: 450–495 nm. Green : 495–570 nm.
Read moreWhat is the frequency of 650 nm?
A red laser emits a very narrow beam at a wavelength of approximately 650 nm (650×10-9m), which corresponds to a frequency of approximately 4.61×10 14 Hz , which is a few hundred terahertz!
Read moreWhat is electromagnetic calculator?
This electromagnetic spectrum calculator converts between four parameters that define electromagnetic radiation: the frequency, the wavelength, the photon energy, and the temperature of a radiating black body for which the radiation curve reaches its maximum (peak wavelength).

Read moreWhat does NASA use the electromagnetic spectrum to study?
NASA’s scientific instruments use the full range of the electromagnetic spectrum to study the Earth, the solar system, and the universe beyond . When you tune your radio, watch TV, send a text message, or pop popcorn in a microwave oven, you are using electromagnetic energy.
Read moreDo astronomers use electromagnetic spectrum?
Astronomers use a number of telescopes sensitive to different parts of the electromagnetic spectrum to study objects in space . Even though all light is fundamentally the same thing, the way that astronomers observe light depends on the portion of the spectrum they wish to study.
Read moreWhat are the 7 regions of electromagnetic spectrum?
In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves . Microwaves (like the ones used in microwave ovens) are a subsection of the radio wave segment of the EM spectrum.
