[#693] The wave of theory of light is based on
Correct Answer

(D) Huyghens' principle

[#694] When a strong beam of light is passed through a colloidal solution, the light will
Correct Answer

(A) Be scattered

Explanation

Solution: When a beam of light is passed through a colloidal solution, colloidal particles scatter light and we can see the path of light. Thus, Tyndall effect is observed.

[#695] Which of these waves can be polarized ?
Correct Answer

(D) Light waves

Explanation

Solution: It is possible to transform unpolarized light into polarized light. A light wave that is vibrating in more than one plane is referred to as unpolarized light. Polarized light waves are light waves in which the vibrations occur in a single plane. The process of transforming unpolarized light into polarized light is known as polarization.
