what is infrared and ultraviolet rays?

Question

Define these two and diffrentiate.

Answer 1

i can say in short which is meaningful


In fared rays means the waves by which we can connect each other.
Ultraviolet rays means the rays which are coming out of sun with 7 colours which affect skin.


We do not have skin disease because in the sky there is Ozone layer.

Answer 2

Infrared radiation is radiation whose wavelength is just longer than that of red light (about 700 nm). Because it has a longer wavelength, it also carries less energy. Infrared light is the form of light that conveys information about an object's temperature, as any object that HAS a temperature gives off some amount of infrared radiation.

Ultraviolet radiation is light whose wavelength is just shorter than that of violet light (about 400 nm). It has more energy than violet light does. UV light is damaging to organisms; it can give you a sunburn when you stay outside too long without sunblock, or it can be used to kill microorganisms in a laboratory.

Answer 3

Infared and Ultraviolet rays are part of the electromagnetic spectrum. Visible light is the part of the spectrum that we can see. Its colour varies with wavelength. Violet has the shortest wavelength and red the longest.
Ultraviolet rays have shorter wavelengths and higher frequencies than violet light.
Infrared rays have longer wavelengths and lower frequencies than red light.

Answer 4

Infra means beneath. Infrared is the invisible waves just beneath red on the radio magnetic spectrum. Ultra means beyond. This is the invisible frequency just beyond violet.

Answer 5

only if the night light has a UV or IR sensor to detect the UV or IR light
