Question

A glass rod of refractive index 1.42 is
immersed in kerosene. The refractive index
of kerosene is 1.42. Then the rod will
a) appear bent b) become invisible
c) appear raised above the liquid
d) none of the above​

Answer 1

Explanation:

When a glass rod of refractive index 1.42 is immersed in kerosene of refractive index 1.42, the rod will be invisible. Transmittance is the incident light that passes through the medium at specific wavelength. Since the rod and kerosene oil have the same refractive index, the rod will be invisible inside the oil.

Answer 2

Answer

option b is the correct
