Intensity of central fringe in interference pattern is 0.01 `W//m^2` then find intensity at a point having path difference` lamda//3 `on screen from centre (in m`W//m^2`)

(a) Why are coherent sources necessary to produce a sustained interference pattern ? (b) In Young's double slit experiment using monochromatic light of wavelength lamda , the intensity of light at a point on the screen where path difference is lamda , is K units. Find out the intensity of light at a point where path difference is lamda//3 .
