Question

the formula of glancing angle​

Answer 1

Answer:

Definition of glancing angle. : the angle between an incident beam (as of X rays or electrons) and the surface upon which it is incident : the complement of the angle of incidence.

The reflected (glancing) angle θ, as shown by experiment, is equal to the incident angle θ. ... But, from geometry, CB and BD are equal to each other and to the distance d times the sine of the reflected angle θ, or d sin θ. Thus, nλ = 2d sin θ, which is the Bragg law.
