The speed of light in a medium is \(200 \times 10^8 cm / s\). Refractive index of a medium is ___________ \(\left( c =3 \times 10^8 m / s \right)\).
- A 2.42
- B 1.0
- C 1.5
- D 1.33
Answer & Solution
Correct Answer
(C) 1.5
Step-by-step Solution
Detailed explanation
\(v = 200 \times 10^8 cm/s = 200 \times 10^8 \times 10^{-2} m/s = 2 \times 10^8 m/s\) \(n = c/v\)
