We have already discussed that the white light is a mixture of seven different colors. When this white light consisting of seven colors falls on an object, then that object absorbs all the colors of the white light except one colour, which it reflects. And it is the...

Recombination of spectrum colors means the combining together of seven colors of white light produced by a prism to give back the white light. This can be done by doing following experiment Experiment to show recombination of colors Take two glass prisms P1 and P2 and...

The dispersion of light is the phenomenon of splitting of a beam of white light into its seven constituent colours when passed through a transparent medium. It was discovered by Isaac Newton in 1666. Newton discovered that light is made up of seven different colours....

The atmosphere of earth consists of different layers of air. Out of these some air layers are hot which have low densities, while the others are cold which have high densities. The hot layers of air behave as optically rarer medium for light rays, whereas the cold...

Total internal reflection is a very interesting phenomenon which takes place when light rays pass from an optically denser medium (e.g. water, glass) into optically rarer medium (e.g. air). Now, we shall discuss the concept of total internal reflection by taking three...
