Blue colour of water in sea is due to

  • A
    refraction of blue light by impurities
  • B
    refraction blue sky by water
  • Correct answer
    C
    scattering of light by water
  • D
    None of the above

Solution

The colour of a colloidal solution depends on the wavelength of the light scattered by the dispersed particles, which in turn depends on the size and the nature of particle. The colour of water in sea is blue due to the scattering of light by water.

Hence, the correct answer is option: 'C'.
