Question

An object placed in one medium when seen from the other medium, it appears to be vertically shifted. Which of the following factors determines the magnitude of shift?

• A. Wavelength of the incident light
• B. Thickness of the denser medium
• C. Refractive index of the medium
• D. All of the above

Answer 1

The correct option is C

Refractive index of the medium

The magnitude of shift depends on the refractive index of the medium, the thickness of the denser medium and the color or wavelength of the incident light. The shift increases with the increase in the refractive index of the medium and also with the increase in the thickness of the denser medium but the shift decreases with the increase in the wavelength of light used.
