What is the exact frequency range of black light?

Answer 1

Light is not a mechanical wave. So no need to have a material medium to pass through. Even through vacuum light can travel. Because it is an electromagnetic wave. As electrical and magnetic disturbance pass on in the form of transverse wave the distance between successive crests is defined as the wavlength of the wave. Here crest means the field intensity becoming maximum.

Answer 2

Black light typically refers to ultraviolet (UV) light in the range of 315-400 nanometers. UV light below 315 nm is sometimes referred to as "black light" as well, but the most common understanding is in the 315-400 nm range.

Answer 3

Black does not have a wavelength. Black is an ABSENCE of light. No light equals black. Nothing there to wave, so no wave length. Nothing. Nada. Zip.

Answer 4

Between 320 nm and 400 nm.

Black is no color / light hence an absence of light has no wavelength.

Answer 5

There are several different types of lasers that all operate on different wavelengths.

Answer 6

Black lights emit ultraviolet light, light at a frequency just above blue light. The exact frequency range of black light is 7.5 x 10 to the 14th power to 3 x 10 to the 16th power Hz

Answer 7

6.2x10‾ ⁷m to 7.5x10‾ ⁷m roughly

Answer 8

Black is the absence of color.
