Huygen's Principle

For light diverging from a finite point source

A plane wave front is incident on a thin prism, thin convex lens and a concave mirror separately. The wave front(s) emerging out from the

A plane wave front $MN$ passing through a system $S$ emerges as a plane wave front $PQ$. The system $S$ could be

Define the term 'wave front of light'. A plane wave front $AB$ propagating from denser medium $\left(1\right)$ into a rarer medium $\left(2\right)$ is incident on the surface $P_1{P}_2$ separating the two media as shown in fig.

Using Huygen's principle, draw the secondary wavelets and obtain the refracted wave front in the diagram.

What is the shape of wavefront due to source is at infinite distance.

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.

A beam of light with a plane wavefront needs to be transformed into one with a convergent spherical wavefront. For this purpose, which of the following may be suitable?

A plane wave passes through a convex lens. The geometrical shape of the wavefront that emerges is

Wavefront is the locus of all points, where the particles of the medium vibrate with the same

The locus of all particles in a medium, vibrating in the same phase is called
