A ray of light is coming from air to water. Which of the following figure shows correct dispersion of light ?

G1 Physics · Accepted Answer

Derived solution: Step 1: Use Snell’s law at each plane interface. For paraxial viewing through a plane surface, apparent depth = real depth × n(observer)/n(object medium). Step 2: Substitute the values given in the question and apply the geometry/sign convention shown. Step 3: On simplification the result is Image 2. Therefore the correct option is B.
