Consider figure. Suppose the voltage applied to A is increased. The diffracted beam will have the maximum at a value of `theta` that

A

will be larger then the earlier value

B

will be the same as the earlier value

C

will be less than the earlier value

D

will depend on the target

Text Solution

Verified by Experts

The correct Answer is:
C

(c ) : As `lamda=(12.27)/(sqrtV)Ã…, "when potential (V) is increased",lamda"decreases. As 2d"sintheta-nlamda,theta"will be less than the earlier value"`.
