  • Two lines, and <img alt="\mathrm{B}" src="https://entrancecorner.oncodecogs.com/gif.latex?%5Cmathrm%7B

Two lines,\mathrm{A} and \mathrm{B} of an \mathrm{ X-Ray}  beam give first order reflection maximum at a glancing angle of \mathrm{ 30^{\circ}} and third order reflection maximum at an angle of \mathrm{ 60^{\circ}}  respectively from the face of the same crystal . If the wave length of the line \mathrm{ B}  is \mathrm{ 0.098 \mathrm{~nm}}  thaw the wave length of line \mathrm{A} will be -

Option: 1

0.170 nm


Option: 2

0.056 nm


Option: 3

0.126 nm


Option: 4

0.092 nm

From Bragg's diffraction- 
\mathrm{2 d \sin \theta=n \lambda}
\mathrm{\text { Here, we have } \theta_1=30^{\circ}, \lambda_1=\text { ? }, n_1=1}
\mathrm{\theta_2=60^{\circ}, \partial_2=0.098 \mathrm{~nm}, n_1=3}
Now, 

 \mathrm{\frac{n_1 \lambda_1}{\sin \theta_1}=\frac{n_2 \lambda_2}{\sin \theta_2}}
