Huygens principle of secondary waves: - Vidyadip

MCQ

Huygens principle of secondary waves:

A
Allow us to find the focal length of a thick convex lens.
B
Give us the magnifying power of the microscope.
C
Is a geometrical method to find, the position of a wave front.
D
Is used to determine the velocity of light.

Answer

Is a geometrical method to find, the position of a wave front.

Explanation:

Huygens's Principle states that every point on a wavefront is a source of secondary wavelets, which spread forward at the same speed.

Thus is enables to find the position of wavefront.
