उत्तर
A diver from inside the water `(n = 4/3)` looks at an object in the air whose natural colour is green. He sees the object as blue.
Explanation:
When a diver inside water `(n = 4/3)` looks at an object in air (rarer medium), the green light from the object undergoes refraction at the water-air interface. Due to dispersion, shorter wavelengths (like blue) refract more, so the green object appears shifted toward blue when viewed from inside the water. Hence, the diver sees the object as blue.
