Problem 17.(adsbygoogle = window.adsbygoogle || []).push({});

The speed of all elctromagnetic waves in empty space is 3*10^8 m/s.

What is the wavelength of X rays emitted at 3.2*10^12 MHz? Answer in m.

This is what I have done;

wavespeed=frequence times wavelength

3*10^8/3.2*10^12 = 9.375 * 10 ^-5 m

I got this answer for the problem but when I submitted the answer it was wrong, what did I do wrong?
