1. The problem statement, all variables and given/known data X-rays are electromagnetic waves with very short wavelengths. Suppose an X-ray has an wavelength of 0.126 nm. What is its frequency? 3. 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?
