Question

HELP PLEASE!

The frequency (F) and length (L) of a wave are related by the following formula: F x L = 3.0 x 1010. Consider that the wavelength of x-rays is 1 x 10−11. What is the frequency of x-rays?

A) 1.1 x 1021



B) 1.1 x 1024

C) 3.0 x 1021

D)3.0 x 1020

Answer 1

`3 * {10}^(10) = f * 1 * {10}^( - 11)`
now find f

Answer 2

What irash is trying to say is the answer is C :)
