Question

Aicharya · Accepted Answer

$\begin{aligned} & \frac{1}{\lambda}=\mathrm{Rz}^2\left(\frac{1}{\mathrm{n}_1^2}-\frac{1}{\mathrm{n}_2^2}\right) \\ & \frac{\frac{1}{\lambda_{\mathrm{L}}}=\mathrm{Rz}^2\left(\frac{1}{1^2}\right)}{\frac{1}{\lambda_{\mathrm{B}}}=\mathrm{Rz}^2\left(\frac{1}{2^2}\right)} \\ & \frac{\lambda_{\mathrm{B}}}{\lambda_{\mathrm{L}}}=4: 1\end{aligned}$
