Question

The wave length of light diminishes $\mu$ times ($\mu$ = 1.33 for water) in a medium. A diver from inside water looks at an object whose natural colour is green. He sees the object as :

• A. Red
• B. Blue
• C. Green
• D. Yellow

Answer 1

The correct option is C Green

Answer is C.
The color of an object depends on the wavelength of the light that it scatters.
For example, a black object scatters little light, and absorbs light at all visual wavelengths; a green object scatters more green light than other colors, which it absorbs more.
Hence, a diver from inside water looks at an object whose natural color is green. He sees the object as green.
