An object is immersed in a fluid . In order that the object becomes, it should
A
have refractive index one
B
absorb all light falling on it
C
behave as a perfect reflector
D
have refractive index exactly matching with that of the surrounding fluid
Text Solution
Verified by Experts
The correct Answer is:
D
We know that if refractive index of a meterial is exactly matching with that of the surrounding fluid, then no refraction or reflection takes plane on their surface of separa-tion, and the object becomes invisible.
