Physics
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
Answer
all of the above
Reason — The shift by which an object appears raised depends on:
- The refractive index of the medium — higher the refractive index of the medium, more is the shift.
- The thickness of the denser medium — thicker the medium, more is the shift
- Colour of the incident light — the shift decreases with the increase in the wavelength of light used.
