When white light is made to pass through a prism, a spectrum of seven colours is formed which shows that white light is a mixture of seven different colours. Prism only acts as a medium for the separation of the seven colours. When light falls on the glass prism,refractiontakes place. Si...
For sustainedinterference of lightto occur, the following conditions must be met: Coherent sources of light are needed. Amplitudes and intensities must be nearly equal to produce sufficient contrast between maxima and minima. The source must be small enough that it can be considered as a point so...
