Important Questions on Huygen's Principle
Define wavefront. Draw the shape of refracted wavefront when the plane incident wave undergoes refraction from an optically denser medium to rarer medium. Hence, prove Snell’s law of refraction.
Why the refracted wavefront of a plane wavefront from the prism will be plane wavefront which is inclined to the incident plane ?
The refracted wavefront of the plane wavefront from prism will be _____ wavefront which is inclined to the incident plane.
Show the behaviour of a plane wavefront in a concave lens.
Draw the diagram of reflected wavefront of a plane wavefront which is incident at an angle to the plane mirror.
Which of the following phenomenon cannot be explained by the Huygens' wave theory?
State Huygen's principle. Using Huygen's wave theory, prove the laws of reflection.
Ray is the locus of points in the light wave’ having the same phase of oscillation at any instant.
There is no backward wavefront possible. Explain.
In Huygen's principle, secondary wavefront at any later time is given by______envelope of secondary wavelets at that time.
In Huygen's principle each point on wavefront acts as a new source of new disturbance called secondary wavelets.
The phenomenon of diffraction can be understood using Huygens principle
According to Huygens principle of secondary wavelets, each particle at a wavefront behaves as _____(an electron/ a photon/ new light source)
Fine rectangular slit is an example of _____ wavefront.
The cylindrical wavefront is usually obtained when the distance between the linear source and screen is small.
