In the adjacent diagram, CP represents a wavefront and AO & BP, the corresponding two rays. Find the condition on theta for constructive interference at P between the ray BP and reflected ray OP.
Plane parallel wavefornts encounter the interference one medium and another as shown below The wave speed is different in the two media. what will happen to the distance between wavefront and the direction of travel wavefronts as the waves enter the second media?
A perpendicular drawn to the wavefront in the direction of propagation of light is
A wavefront and a ray of light are
What is a wavefront ? State its relation with ray of light.
Wavefront of a wave has direction with wave motion
