Physics
An object when placed in a rarer medium and is viewed from a denser medium appears to be at a …………… distance than its real distance.
- smaller
- greater
- same
- cannot say
Answer
greater
Reason — When an object is placed in a rarer medium (like air) and viewed from a denser medium (like water), the light rays coming from object when passing from air to water, bend towards the normal and appear to be coming from a new point such that the distance appears greater than the actual distance.

An object in a denser medium when viewed from a rarer medium appears to be raised. The shift is maximum for:
- red light
- violet light
- yellow light
- green light
The shift by which an object appears to be raised depends on:
- the refractive index of the medium
- the thickness of denser medium
- the wavelength of incident light
- all of the above
