What is ultraviolet in electromagnetic spectrum?
UV (Ultraviolet) Light refers to the region of the electromagnetic spectrum between visible light and X-rays, with a wavelength falling between 400 and 10 nanometers.
Is ultraviolet electromagnetic waves?
Ultraviolet radiation is the portion of the electromagnetic spectrum extending from the violet, or short-wavelength, end of the visible light range to the X-ray region.
What are ultraviolet electromagnetic waves used for?
UV radiation is widely used in industrial processes and in medical and dental practices for a variety of purposes, such as killing bacteria, creating fluorescent effects, curing inks and resins, phototherapy and suntanning.
What is the wavelength of ultraviolet waves?
The UV region covers the wavelength range 100-400 nm and is divided into three bands: UVA (315-400 nm) UVB (280-315 nm) UVC (100-280 nm).
Why is ultraviolet called Ultraviolet?
“Ultraviolet” means “beyond violet” (from Latin ultra, “beyond”), violet being the color of the highest frequencies of visible light. Ultraviolet has a higher frequency (thus a shorter wavelength) than violet light.
What are the properties of ultraviolet waves?
Ultraviolet light is located between X-radiation and visible light. UV has a higher frequency and shorter wavelength than visible light, and it has a lower frequency and longer wavelength than X-radiation. UV with its longer wavelength and less energy is less penetrating than X-ray and is sometimes absorbed by matter.
Where is ultraviolet located on the electromagnetic spectrum?
Ultraviolet radiation lies between visible light and X-rays along the electromagnetic spectrum. UV “light” spans a range of wavelengths between about 10 and 400 nanometers.
What are examples of ultraviolet waves?
Examples of Ultraviolet Waves
- A UV light equipped disinfectant.
- A UV lamp.
- Sterilizing a room with the help of UV rays.
- A UV lamp curing skin diseases.
- UV bed for tan removal.
- UV rays creating northern lights.
- UV liight used for decoration.
Where is ultraviolet radiation located on the electromagnetic spectrum?
Ultraviolet radiation lies between visible light and X-rays along the electromagnetic spectrum. UV “light” spans a range of wavelengths between about 10 and 400 nanometers. The wavelength of violet light is around 400 nanometers (or 4,000 Å).
Where are ultraviolet waves found?
OUR SUN The Sun
ULTRAVIOLET LIGHT FROM OUR SUN The Sun is a source of the full spectrum of ultraviolet radiation, which is commonly subdivided into UV-A, UV-B, and UV-C. These are the classifications most often used in Earth sciences. UV-C rays are the most harmful and are almost completely absorbed by our atmosphere.
What detects ultraviolet waves?
Ultraviolet can be detected by suitable photodiodes and photocathodes, which can be tailored to be sensitive to different parts of the UV spectrum. Sensitive UV photomultipliers are available. Spectrometers and radiometers are made for measurement of UV radiation. Silicon detectors are used across the spectrum.
Which statement about ultraviolet waves is correct?
Detailed Solution. The correct answer is It is a longitudinal wave. Ultraviolet light also called UV light has a wavelength between 10 and 400 nm which is shorter than visible light but it is larger than the X-rays.
What are the dangers of UV light?
Location – the risks are higher in tropical areas nearer the equator.
Is ultraviolet light the most energetic?
Ultraviolet is the most energetic form of visible electromagnetic radiation – light, in other words. There are more energetic forms of electromagnetic radiation such as X-rays. These are not in the visible light range. So what is this range, and what does energetic mean? All electromagnetic energy has a frequency and wavelength.
What are electromagnetic spectrum harmful effects?
What electromagnetic spectrum are harmful to humans? T he most dangerous frequencies of electromagnetic energy are X-rays, gamma rays, ultraviolet light and microwaves. X-rays, gamma rays and UV light can damage living tissues, and microwaves can cook them. What are the bad effects of electromagnetic radiation on living things?
Does ultraviolet light have more energy than infrared light?
The difference in energy levels between orbitals that is observed when an infrared photon is produced is very small compared to what happens when an ultraviolet wave is produced. Therefore infrared photons have relatively little energy and “big-drop” ultraviolet photons have relatively great energy.
