When a body of refractive index \(\boldsymbol{\mu}=\mathrm{1 . 4}\) is put into a liquid, the body becomes invisible. What would be the refractive index of the medium?
- A \(\mu=0.7\)
- B \(\mu=1\)
- C \(\mu=1.4\)
- D \(\mu=2.4\)
Answer & Solution
Correct Answer
(C) \(\mu=1.4\)
Step-by-step Solution
Detailed explanation
A body becomes invisible when placed in a liquid if the refractive index of the body is equal to the refractive index of the liquid medium. This is because there is no refraction or reflection at the interface between the body and the liquid, as the light rays pass through…
