UltaViolet Light:Ultraviolet light is a part of the electromagnetic spectrum. Ultraviolet rays have frequencies greater than the frequency of visible light but lower than the frequency of X-rays. The wavelength of ultraviolet light is shorter than visible light and longer than that of X-rays. O...
What is the wavelength of the light in water?Refractive index:The parameter that determines the rate of passing the light through the medium in the context of time is called the refractive index. Mathematically the refractive index of the medium is calcul...
visible light, ultraviolet (UV) and gamma radiation (γ), the wavelength is more often specified in nanometers (nm) or angstroms (Å). Nanometers are units of 10-9m, and angstroms are units of 10-10m.
Red light therapy, also known as LED therapy, is gaining popularity in the skin care world for its potential anti-aging benefits. Dr. Rachel Nazarian, a board-certified dermatologist in New York, told "CBS Mornings Plus" that LED, or light emitting diodes, create a narrow wavelength that ...

The truth is, even if you could see through someone’s clothes using your X-ray vision (which, by the way, you can), it’s only their bones that you would be able to see. X-rays have a very small wavelength and high amounts of energy, which is why they can penetrate ...
Violet light is the segment of the visible light spectrum that occupies the wavelengths ranging from approximately 380 nm - 450 nm (or equivalently, 3800 Å - 4500 Å). This short wavelength aligns with high-frequency electromagnetic waves, which give its characteristic appearance at the border...
The extreme part of the red region in excess of 700 nm is often referred to as infrared orfar-redlight. White lightis that in which all the wavelengths of visible light are present whiledarkhas no visible wavelength. But theultraviolet radiationis packed with excessive amounts of energy. ...
The material in an LED is selected so that the wavelength of the released photons falls within the visible portion of the light spectrum. Different materials produce photons at different wavelengths, which appear as light of different colors. LED Anatomy The two basic types of LEDs are indicator...
b. What is the wavelength of light emitted when the hydrogen atom undergoes a transition from level n = 5 to level n = 2? Electromagnetic radiation Electromagnetic radiation and the wavelengths that are part of it are ...
