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

$3 \times {10}^{10} = f \times 1 \times {10}^{ - 11}$
now find f
