X-rays have a wavelength small enough to image individual atoms, but are challenging to detect because of their typical frequency. Suppose an X-ray camera uses X-rays with a wavelength of 8.38nm . Calculate the frequency of the X-rays. Round your answer to 3 significant digits.

Explanation:

Given: [tex]\lambda = 8.38\:\text{nm} = 8.38×10^{-9}\:\text{m}[/tex]

Its frequency [tex]\nu[/tex] is defined as

[tex]\nu = \dfrac{c}{\lambda} = \dfrac{3×10^8\:\text{m/s}}{8.38×10^{-9}\:\text{m}}[/tex]

[tex]\:\:\:\:= 3.58×10^{16}\:\text{Hz}[/tex]
