X-ray diffraction pattern of a crystal is given below. It undergoes first order reflection at a Bragg angle of 30 degrees from a crystal.
0.10 nm
0.15 nm
0.20 nm
0.25 nm
The given X-ray diffraction pattern is due to the constructive interference of X-rays diffracted by the crystal planes. According to Bragg's law, the condition for constructive interference is given by , where d is the interplanar spacing, is the angle of incidence, is the wavelength of the X-rays, and n is an integer.
As it undergoes first order reflection at a Bragg angle of 30 degrees from a crystal.
Therefore, we can calculate the interplanar spacing (d) using the formula as:
