Question 645: Atoms & Nuclei

Question

The interplanar distance in a crystal is 2.8 $$ 	imes $$ 10$$-$$8 m. The value of maximum wavelength which can be diffracted

Accepted Answer

2dsin$$	heta $$ = n$$\lambda $$
$$ \because $$ $$ - 1 \le \sin 	heta  \le 1$$
Therefore $$\lambda $$
max
= 2d
$$ \Rightarrow $$ $$\lambda $$
max
= 2 $$ 	imes $$ 2.8 $$ 	imes $$ 10
