what is the frequency of ultraviolet radiation ?

Question

Ultraviolet radiation falls in the wavelength region of 1.00×10^-8 to 1.00×10^-7 meters.

What is the frequency of ultraviolet radiation that has a wavelength of 1.00×10^-8 m?

Frequency =  _______sec^-1

Answer 1

frequency = speed of light divided by wavelength

f = c/λ = (3.00 x 10⁸ m/s) / (1.00 x 10^-8 m) = 3.00 x 10¹⁶ sec^-1
