Question

Braggs law is given by equation:

• A. $n\lambda =2\theta sin\theta$
• B. $n\lambda =2dsin\theta$
• C. $2n\lambda =dsin\theta$
• D. $n\lambda =\frac{1}{2}dsin\theta$

Answer 1

The correct option is B $n\lambda =2dsin\theta$

Bragg's law equation is $n\lambda =2dsin\theta$

where $n$ is the order of reflection.

So, option ( B ) is correct.
