Relation between ray and wavefront is ______.
OPTIONS
Rays are parallel to wavefront
Rays are at acute angle to wavefront
Rays are tangential to wavefront
Rays are perpendicular to wavefront

SOLUTION
Relation between ray and wavefront is rays are perpendicular to wavefront.
Explanation:The new wavefront is the forward envelope of the secondary waves, according to Huygens' architecture. Secondary waves are spherical when the speed of light is independent of direction. The rays are perpendicular to the wavefronts at this point.
Concept: Huygens' Principle
