An object is immersed in a fluid of refractive index ' $\mu$ '. In order that the object
becomes invisible when observed from outside, it should
have refractive index equal to one.
have refractive index same as surrounding fluid, that is ' $\mu$ '
absorb all light falling on it.
behave as a perfect reflector.
Solution
An object is immersed in a fluid of refractive index 'meu'. In order that the object becomes invisible when observed from outside, it should have refractive index same as surrounding fluid, that is meu
