Huygen's theory of secondary waves can be used of find

Velocity of light

The wavelength of light

Wave front geometrically

Magnifying power of microscope

Solution

Huygens' principle states that every point on a wave front may be considered as a source of secondary waves. The word interference is used to describe the superposition of two waves, whereas diffraction is interference produced by several waves. By this principle we can find the exact position of the next ripple/wave front that is to be produced.
