A and b please How can two waves from coherent sources reinforce each other? Select all the correct choices.None of the other choices are correctBy interfering destructively.By meeting each other in phase.By interfering constructively.OBy meeting each other out of phase. The double-slit experiment is said to demonstrate the wave nature of light. How does it do that? Select the best choice.By using more than a single slit.By splitting the light beam into sub-beams.None of the other choices are correct.OBy obeying the condition d <

A. waves from coherent sources have same frequency , wavelength , phase and other properties. So its just like two same waves are travelling from different sources. when these waves meet they interfere with each other. The point at which the amplitude of the waves matches they reinforce each other, the resultant wave have higher amplitude than the interfering waves and is called constructive interference while the point at which there amplitude are opposite they cancel each other , the resultant wave has less amplitude than interfering waves and is called destructive interference. Therefore waves from coherent sources reinforce each other by interfering constructively.B. In double slit experiment light from a source is made to pass from two very narrow slits and the made to fall on a screen. The result is a pattern of dark and bright bands of light which are alternate to each other. It is only possible when there is interference between the rays passing through the slits. And interference is a wave phenomenon. Thus double slit experiment demonstrate wave nature of light by showing light rays can interfere with each other.
