The diffraction of barium with X-radiation of wavelength 2.29Å gives a first – order reflection at 30°. What is the distance between the diffracted planes.
Text Solution
Verified by ExpertsThe correct answer is:
C
Using Bragg's equation 
, where d is the distance between two diffracted planes, 
the angle to have maximum intensity of diffracted X-ray beam, 
the order of reflection and 
is the wavelength
