Question

X rays of wavelength 0.154 nm are diffracted from a crystal at angle

Answer 1

Hi..


4. X rays of wavelength 0.154 nm are diffracted from a crystal at an angle of 14.17O
. Assuming that
n=1 calculate the distance (in pm) between the layers in the crystal.
Convert to picometers
0.154 nm (1000 pm/1nm) = 154 pm
Plug in given values to Equation:
2 d sinθ = nλ
d = nλ/ 2 sinθ
d=(1)(154 pm)/ (2 sin(14.17))
d=314 pm
..

Hope this helps u!!
