Question #133325

The atomic planes in a graphite crystal are separated by 335 pm. At what angle would you find the first-order (n = 1) diffraction of 0.154 nm X-rays from a graphite crystal? Shows the calculation steps.

Expert's answer

In application of Braggs law

"2d.Sin\\theta=n\\lambda"

"Sin \\theta=" "n\\lambda\\over 2d"

"\\theta=unknown"

"n=1"

"\\lambda=154pm"

"d=335pm"

"\\therefore" "Sin \\theta" "=" "1\\times 154\\over 2\\times 335" "=0.229"

"Sin \\theta =0.229"

"\\theta= 13.24\u00b0"
