What is ultraviolet and infrared region?
What is ultraviolet and infrared region?
The key difference between infrared and ultraviolet radiation is that the wavelength of infrared radiation is longer than that of visible light, whereas the wavelength of ultraviolet radiation is shorter than the wavelength of visible light. Infrared and ultraviolet radiation are two types of electromagnetic radiation.
What are three regions of ultraviolet?
Just as visible light consists of different colours that become apparent in a rainbow, the UV radiation spectrum is divided into three regions called UVA, UVB and UVC. As sunlight passes through the atmosphere, all UVC and most UVB is absorbed by ozone, water vapour, oxygen and carbon dioxide.
What is the region of ultraviolet frequency?
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). Ultraviolet radiation oscillates at rates between about 800 terahertz (THz or 1012 hertz) and 30,000 THz.
What is visible infrared?
Infrared Light (IR) is the light found just past what is visible to the human eye. Near-Infrared Light (NIR) is the section of electromagnetic radiation (EMR) wavelengths nearest to the normal range but just past what we can see. Visible light is the smallest section of the electromagnetic (EM) radiation field.
What is ultraviolet visible and infrared light?
Light (also referred to in professional literature as radiation) is best thought of as a spectrum consisting of ultraviolet light (UV) at the short end, visible light in the center, and infrared (IR) wavelengths at the long end.
What are visible waves?
Visible light waves are the only wavelengths of the electromagnetic spectrum that humans can see. The different wavelengths of visible light are seen as the colors of the rainbow: red, orange, yellow, green, blue, indigo, and violet.
What are uses of visible light?
We often use visible light images to see clouds and to help predict the weather. We not only look at the Earth from space but we can also look at other planets from space. This is a visible light image of the planet Jupiter.
Can humans see visible light?
The visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view. More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.
What is infrared used for?
Infrared radiation uses Among the most well-known are heat sensors, thermal imaging and night vision equipment. In communications and networking, infrared light is used in wired and wireless operations.
