An object is immersed in a fluid of refractive index ' \(\mu\) '. In order that the object
becomes invisible when observed from outside, it should
- A have refractive index equal to one.
- B have refractive index same as surrounding fluid, that is ' \(\mu\) '
- C absorb all light falling on it.
- D behave as a perfect reflector.
Answer & Solution
Correct Answer
(B) have refractive index same as surrounding fluid, that is ' \(\mu\) '
Step-by-step Solution
Detailed explanation
For an object to be invisible in a fluid, there must be no refraction or reflection at its surface. This occurs when its refractive index matches that of the surrounding fluid.
