Question

An object in a denser medium when viewed from a rarer medium appears to be raised. The shift is maximum for :

• A. red light
• B. violet light
• C. yellow light
• D. green light

Answer 1

The correct option is B violet light

An object in a denser medium when viewed from a rarer medium appears to be raised. This is due to refraction.
The dispersion of white light into a spectrum occurs because the different colors are refracted by different amounts by the water medium. Violet light is refracted most by the medium and red light is refracted least.
