What is actual process of interference?
Anjali said:

Interference is the phenomenon in which two waves superpose each other to form a resultant wave of greater or lower amplitude.

Please make an elaborate explanation.

Interference :
When two different waves having different velocities are overlap with each other and produce a new one it is called Interference. In the case of rain water it happens.

Water having lightly packed molecules. So the oil spread easily on the water.

This is not only on rainy day if we threw oil films on water in light there also we can observe interference pattern.

Due to oil, a thin film is formed on water surface. When light falls upon it, then it undergo multiple reflections at its top and bottom layers. Interference takes place between these reflected rays. Now depending upon the angle of incidence/reflection, thickness of the oil film, viewing angle etc., different colors are produced on the film.

The different waves coming from sun falls on water and starts coming in a same phase.

It has to be due prism like formation. Where the white light splits into various colors the effect of interference could be to the extent of making these colors bright. So both diffraction n interference could be responsible.

On the surfaces of water thin layer of oil produced partial refraction and reflection, the refracted light will also reflected from the water surface, due to theses reflected non monochromatic rays interference is occurred.
