Are a geometrical method to find a wavefront
Are used to determine the velocity of light
Explain the reflection of plane wavefront from concave mirror.
Write the limitation of Huygen's principle.
Huygen wave theory allows us to know
Wave front is locus of all the points where the particles of the medium vibrate with the same
