Huygen’s principle of secondary wavelets can be used to
a) deduce the laws of reflection of light
b) deduce the laws of refraction of light
c) explain the transverse nature of light waves
d) predict the location of a wavefront as time passes

Huygen's principle states that every point on a wave-front may be considered a source of secondary spherical wavelets which spread out in the forward direction at the speed of light. The new wave-front is the tangential surface to all of these secondary wavelets. They explain reflection and refraction . It will not explain transverse nature.
