Answer to Question #257220 in Physics for Ayomide

Question

Calculate the energy carried by an x-rays of wavelength 7.5×10^-10m(h=6.6×10^-34js, vorc=3×10⁸m/s)(Hmt:E=hc)

Answer 1

We can find the energy carried by an x-rays of wavelength $\lambda$ as follows:

$E=\dfrac{hc}{\lambda}=\dfrac{6.626\times10^{-34}\ J\times s\times3.0\times10^8\ \dfrac{m}{s}}{7.5\times10^{-10}\ m}=2.65\times10^{-16}\ J.$
