Physics
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
Answer
violet light
Reason — When light travels from a rarer medium to a denser one, it bends towards the normal. The amount of bending (and consequently the apparent shift in the position of the object) is inversely proportional to the wavelength of light, which is characterized by its color.
This means that shorter wavelengths (such as violet light) will experience a greater degree of refraction compared to longer wavelengths (such as red light).
