Hi dear,
I have tried to add the most simple words in in most simple way of answering....hope you get it....
You may have noticed, when a film of oil floating in a puddle reflects light, a swirling mass of rainbow colors seem to magically appear. The cause of this phenomenon is interference between light waves. A soap bubble floating in the air also reflects a variety of beautiful colors.
INTERFERENCE is the process in which two or more waves of the same frequency - be it light, sound, or other electromagnetic waves - either reinforce or cancel each other, the amplitude of the resulting wave being equal to the sum of the amplitudes of the combining waves.
Waves don't normally reflect when they strike one another. Instead, they combine. If the amplitudes of two waves have the same sign - either both positive or both negative, they will add together to form a wave with a larger amplitude. For example, if at a given instant in time and location along the medium, the crest of one wave meets the crest of a second wave, they will interfere in such a manner as to produce a "super-crest." Similarly, the interference of a trough and a trough interfere constructively to produce a "super-trough." This is called constructive interference. If the two amplitudes have opposite signs, they will subtract to form a combined wave with a lower amplitude. For example, the interaction of a crest with a trough is an example of destructive interference. Destructive interference has the tendency to decrease the resulting amount of displacement of the medium.
If light is passed through two slits close together, the waves will interact, and the diffracted beam can be seen on a screen to have bright and dark bands on it. The bright bands show constructive interference of light. The dark bands show destructive interference of light.
Please note......Young's interference experiment, also known as the double-slit interferometer, was the original version of the modern double-slit experiment, performed at the beginning of the nineteenth century by Thomas Young (1773-1829) a British scientist. This experiment played a major role in the general acceptance of the wave theory of light.
