Wavelength, frequency, and energy carried by each photon (light quantum).
Ultraviolet and infrared wavelengths are invisible to the naked (human) eye. cw: Yes, in general, you can't see light with higher energy than violet or lower than red. On the low end, that energy level starts with infrared. On the high side, that energy level starts with ultraviolet. Between is the visible light spectrum.
Astronomers use infrared light to map the dust in between stars.
This has to do with the electromagnetic spectrum. Whether you know it or not, Gamma-rays, ultraviolet, X-rays, microwaves, visible light, infrared, and radio/tv waves are all the same thing, just in different doses. Infrared literally means "below-red", while ultraviolet means (beyond or above violet, or purple). With fore-said spectrum, visible lights highest frequency color appears to us as purple. At a slightly lower frequency we observe blue, then green, followed by yellow, and eventually red. In between each of these colors we observe intermediate colors like magenta, teal, orange and pink. At a frequency lower than, or below, red, we begin to enter the infrared area of the electromagnetic spectrum. Above purple, we enter the ultraviolet area of the electromagnetic spectrum.
Ultraviolet light (UV light) is light of shorter wavelength than the visible spectrum. Many insects, like bees, see mostly UV light so they can find plants with nectar. Sunlight contains UV light and can tan but also damage your skin if you stay outside too long on a sunny day.Answer:Visible light is electromagnet radiation of different frequencies. The different frequencies are the different colors. Just outside the range of frequencies (colors) humans can see are infrared and ultraviolet. Ultraviolet is higher frequency and infrared is lower.Note: Higher frequencies are shorter wavelengths and lower frequencies are longer wavelengths.Visible light is electromagnet radiation of different frequencies. The different frequencies are the different colors. Just outside the range of frequencies (colors) humans can see are infrared and ultraviolet. Ultraviolet is higher and infrared is lower
They are sometimes called "black lights".
There are a lot of things that infrared lights are used for, primarily sight enhacements. Just to name a few, infrared lights are used for night vision, thermography, hyperspectral imagery, tracking, and heating.
Radio and microwaves are longer than visible light. So are heat (infrared) waves. Ultraviolet waves are shorter than visible light. So are X-rays and gamma rays.
Motion sensing lights use a passive system that detects infrared energy. These sensors are known as PIR (passive infrared) detectors or pyroelectric sensors. Human skin averages to be 93 degrees F, which radiates infrared energy in a wavelength that is between 9 and 10 micrometers. The sensors dectect quick movement of objects that radiate between 8 to 12 micrometers of infrared energy.
yes
no, because ultraviolet rays are just above seeing and with ultraviolet lights, you see a more violet color.
Ultraviolet IS light. It comes from the sun. It's why we wear sun screen.
