What spectral range is 1000nm?
The Electromagnetic Spectrum The boundaries shown in the above figures are approximate and there are overlaps between two adjacent regions. Wavelength units: 1 mm = 1000 µm; 1 µm = 1000 nm. Radio Waves: 10 cm to 10 km wavelength. Infrared: 0.7 to 300 µm wavelength.
What are the 7 regions in EM spectrum?
The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.
What type of electromagnetic waves cause sunburns?
Ultraviolet light is a type of electromagnetic radiation that makes black-light posters glow, and is responsible for summer tans — and sunburns. However, too much exposure to UV radiation is damaging to living tissue.
What region is 200 nm?
ultraviolet region
The visible region of the spectrum comprises photon energies of 36 to 72 kcal/mole, and the near ultraviolet region, out to 200 nm, extends this energy range to 143 kcal/mole.
What are 3 types of harmful waves that our atmosphere protects us from?
However, the Earth’s atmosphere protects us from exposure to a range of higher energy waves that can be harmful to life. Gamma rays, x-rays, and some ultraviolet waves are “ionizing,” meaning these waves have such a high energy that they can knock electrons out of atoms.
What are the types of radiation?
There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects.
Which section of the EM spectrum is responsible for sunburn?
The far ultraviolet, abbreviated FUV, lies between the near and extreme ultraviolet regions. It is the least explored of the three regions. Our Sun emits light at all the different wavelengths in electromagnetic spectrum, but it is ultraviolet waves that are responsible for causing our sunburns.
What radiation causes sunburn?
Too much ultraviolet radiation (UV) from sunlight is dangerous. Nearly half of UV radiation is received between 10 a.m. and 4 p.m., when the sun’s rays are the strongest. Even on a cloudy day, you can be sunburned by UV radiation.
What is the visible light spectrum in order?
The order of wavelengths can be remembered by the mnemonic “Roy G Biv” for red, orange, yellow, green, blue, indigo (the blue/violet border), and violet.
