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 moreHow does NASA use electromagnetic waves?
NASA utilizes the VHF band by airborne sensors to study the thickness of sea ice . NASA astronauts use UHF systems as backups for their voice communication systems. NASA also used these frequencies to remotely sense the Earth’s surface (e.g. soil moisture with the SMAP mission) and atmosphere.5 Eyl 2018
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.
