A) \[\frac{n}{\mu },\frac{\lambda }{\mu },v\]
B) \[n,\lambda \frac{v}{\mu }\]
C) \[n,\frac{\lambda }{\mu },\frac{v}{\mu }\]
D) \[\frac{n}{\mu },\frac{\lambda }{\mu },\frac{v}{\mu }\]
Correct Answer: C
Solution :
When electromagnetic wave enters in other medium, frequency remains unchanged while wavelength and velocity become \[\frac{1}{\mu }\] times. So, after entering from air to glass slab \[(\mu )\], frequency remains n, wavelength \[\lambda =\frac{\lambda }{\mu }\] and velocity of light in medium \[v=\frac{v}{\mu }.\].
