Light of wavelength in medium enters into medium through a plane surface. If the frequency of light is and the ratio of speed in medium to that is medium is , the absolute refractive index of medium is,
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
Absolute refractive index of medium A, μA=cνAλ=3×1085×1014×300×10-9=2 Refractive index is inversely proportional to the velocity of light. ⇒μBμA=vAvB=45 ⇒μB=μA45=85 ⇒μB=1.6
