what does nm stand for (UVA - 320 to 400 nm )?

Answer 1

Nanometre (nm, 10-9 m), a thousand-millionth of a metre

(NM may stand for:

Air Madrid and Mount Cook Airline IATA airline designator
Neurofiber Mitosis, a nerve disease, sometimes confused with neurofibromatosis
nm (Unix), a computer program used as an aid for debugging. List symbols from object files or modules.
Nautical mile (nm)
New Mexico (NM)
Newton metre (N m or N·m), a unit of moment

"Not much" (nm), in Internet slang
"Never mind" (nm), in Internet slang
Non-metallic power cable, widely used in electrical house wiring
Northwestern Mutual, a life insurance and financial services company based in Milwaukee, WI
Network Module
Network marketing
"Near mint" (NM), in Antique collecting, particularly comic books and trading cards. )

λ = wavelength of a sound wave or electromagnetic wave IN METERS/NENOMETERS.

Answer 2

In this instance, the abbreviation 'nm' stands for Nanometer (.000000001 (10^-9) of a meter) - a unit of measurement and in the case of Ultra Violet Light or UVA, it is used to indicate wavelength. Ultraviolet light is just beyond the range of visible light on the electromagnetic spectrum. There are different wavelengths of Ultraviolet rays and in the case of your example listed above, the wavelength size or 'frequency' is 320-400 Nanometers. Hope this helps.

Answer 3

nm stands for Nanometer. Nanometer is a measure of distance.

1 nm = 1 * 10 ^ (-9) meters (Ten raised to the power of -9)

Answer 4

nanometers. It is a very small unit of length. The ultraviolet light has a wavelength equal to 320 to 400 nanometers.

Answer 5

Uv Light Stand

Answer 6

nm stands for nano-metre. Nano meter is defined as 10^-9 meters or you can conceive that if you break apart a metre into 1000000000 equal parts, one of these is a nanometre or nm.
As wavelength and amplitude of light waves are very very small, they are represented in nano metres instead of meters.

Answer 7

nm is nano-meters, or .000000001 (10^-9) of a meter, or very, very small. Basically, that's telling you the signature wavelengths of UV-A light.

(Wavelengths are how far the light moves as it does one up-and-down pattern of intensity.)

Answer 8

nm stands for nano metre ( smaller unit of distance,1nm=10^-9m)

Answer 9

nanometers. (10^-9 m)

Answer 10

It's you , huh? that's what your avatar name says. Nano meter. 1 nano meter is equivalent to .000000001 meter. God, I hate doing your home work for you.
