Question

if the light source is point-size,then what type of waveform is formed hindi me​

Answer 1

Answer:

For a point source, the waveform produced is SPHERICAL.

Explanation:

Imagine a point source placed at a reference origin.

Now, as the waves radiate outwards from the source we can clearly imagine a sphere at a particular radius from the source at which all the particles of the wave are in the same phase.

So, at particular radii from the source, as all the particles will remain in the same phase, we will call that sphere as the waveform.

So, spherical waveform is produced.
