A) 9: 7
B) 8 : 1
C) 81 : 49
D) 81 : 7
Correct Answer: C
Solution :
The ratio of intensities of maxima and minima \[\frac{{{I}_{\max }}}{{{I}_{\min }}}=\frac{{{(\sqrt{{{I}_{1}}}+\sqrt{{{I}_{2}}})}^{2}}}{{{(\sqrt{{{I}_{1}}}-\sqrt{{{I}_{2}}})}^{2}}}=\frac{{{(\sqrt{64}+\sqrt{1})}^{2}}}{{{(\sqrt{64}-\sqrt{1})}^{2}}}\] \[\frac{{{I}_{\max }}}{{{I}_{\min }}}=\frac{{{(8+1)}^{2}}}{{{(8-1)}^{2}}}=\frac{81}{49}\]You need to login to perform this action.
