Optics Question 737
Question: Which of the following is a correct relation
[MP PET 1997]
Options:
A) $ _{a}{\mu _{r}}= _{a}{\mu _{w}}\times _{r}{\mu _{\omega }} $
B) $ _{a}{\mu _{r}}\times _{r}{\mu _{w}}= _{w}{\mu _{a}} $
C) $ _{a}{\mu _{r}}\times _{r}{\mu _{a}}=0 $
D) $ _{a}{\mu _{r}}/ _{w}{\mu _{r}}= _{a}{\mu _{w}} $
Show Answer
Answer:
Correct Answer: D
Solution:
$ \frac{ _{a}{\mu _{r}}}{ _{w}{\mu _{r}}}=\frac{{\mu _{r}}/{\mu _{a}}}{{\mu _{r}}/{\mu _{w}}}=\frac{{\mu _{w}}}{{\mu _{a}}}= _{a}{\mu _{w}} $
