Find the energy, the frequency and the momentum of an X-ray photon of wavelength 0.10 nm.

Explanation

Given `lambda=0.1nm `
(a) `Energy =(hc)/lambda `
` =(1242eVnm)/(0.1nm) `
` =12420eV `ltbr.` 12.42KeV `
` ~~12.4KeV `
` (b) Frequency=c/lambda=(3xx10^8)/(0.1xx10^-9) `
` 3xx10^8Hz `
(c) Momentum
` E/c=(12.4xx10^3xx1.6xx10^-19)/(3xx10^8) `
` 6.613xx10^-24Kg-m//s `
` 6.62xx10^-24Kg-m//s `
