A) \[\left( \frac{\pi }{2}-A \right)\]
B) \[\left( 2\pi -\frac{A}{2} \right)\]
C) \[\left( \frac{\pi -A}{2} \right)\]
D) \[(\pi -2A)\]
Correct Answer: D
Solution :
Key Idea:\[\sin ({{90}^{o}}-\theta )=\cos \theta \] The refractive index \[(\mu )\] of a prism of angle\[A\], and minimum deviation\[{{\delta }_{m}}\], is given by \[\mu =\frac{\left( \frac{A+{{\delta }_{m}}}{2} \right)}{\sin A/2}\]You need to login to perform this action.
