Question
If a light ray from air enters three different media in such a way that the refracted angles are 450, 300 and 600 respectively. Identify the right statement with respect to the optical density of these media.
Answer: Option B
:
B
Angle of incidence i is same for all three media. Angle of refraction for the different media are:
rm1=45∘
rm2=30∘
rm3=60∘
Deviation will be highest for medium with highest optical density. Clearly, the deviation is highest (30∘) for Medium 2. Hence, Medium 2 has highest optical density.
