Homework Statement


X-rays are electromagnetic waves with very short wavelengths. Suppose an X-ray has an wavelength of 0.126 nm. What is its frequency?

The Attempt at a Solution


I tried (1)/(1.26E-10)=7936507937, which is in Hz, but they want it to GHz, so i converted it and got 7.94 GHz but it's incorrect? Any idea where I'm going wrong?

Wavelength is not the inverse of frequency.

wavelength x frequency = speed
 
Chi Meson said:
Wavelength is not the inverse of frequency.

wavelength x frequency = speed

So what is the speed? Is it the constant c, 3E8? And will using that give me my answer in Hz?
 
yes its c, all EM radiations have speed c
