Question:medium

When a body of refractive index \( \mu = 1.4 \) is put into a liquid, the body becomes invisible. What would be the refractive index of the medium?

Show Hint

An object becomes invisible in a medium when both have the same refractive index, because there is no significant refraction at the boundary.

Updated On: May 5, 2026

\( \mu = 1 \)
\( \mu = 0.7 \)
\( \mu = 2.4 \)
\( \mu = 1.4 \)

Show Solution

The Correct Option is D
