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 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.
Read moreWhat are the uses of microwaves?
Microwaves are widely used in modern technology, for example in point-to-point communication links, wireless networks, microwave radio relay networks, radar, satellite and spacecraft communication, medical diathermy and cancer treatment, remote sensing, radio astronomy, particle accelerators, spectroscopy, industrial …
