A) \[n\lambda =2d\sin \theta \]
B) \[\lambda =2\,nd\sin \theta \]
C) \[2n\,\lambda =d\sin \theta \]
D) \[n\lambda =2\theta \sin \theta \]
Correct Answer: A
Solution :
When a beam of monochromatic X-ray strikes two planes of atom in a crystal at a certain angle 9, it is reflected. Intensity of the reflected beam is maximum if\[n\lambda =2d\,\sin \theta \] This is called Braggs equation, where, \[n=\] order of reflection (1, 2,3... etc.)\[\lambda =\] wavelength of X-ray light used \[d=\] distance between two planesYou need to login to perform this action.
