Wat is the wavelength and frequency of uv rays???

Question

Please any info you no and with the wavelength, frequency bit, if possible could u put it in 10 -2, 0.0000000001, 321nm and wat eva

THX GUYS!!!

Answer 1

Here's a handy diagram of the EM spectrum.

As you can see UV begins at a bit under 400nm wavelength, say around 300 nm since the line is kinda blurry. And then since it is a continuous spectrum, there is no hard and fast limit as to when UV stops and X-Rays start, for the sake of a round number though, you could use 10nm.

The frequencies that correspond to those wavelengths can be calculated with the formula f = c/λ

f = 3.0*10^8 / (300 * 10^-9)

f = 1.0 * 10^15

f = 1.0 PHz

f = 3.0*10^8 / (10 * 10^-9)

f = 3.0 * 10^16

f = 30 PHz

So it could be said that UV has a wavelength between 10 and 300nm, and a frequency between 1 and 30 PetaHertz.
