Light from two coherent sources of the same amplitude A and wavelength `lambda` illuminates the screen. The intensity of the central maximum is `I_(0)`. If the sources were incoherent, the intensity at the same point will be

Light from two coherrent sources of same amplitude (A) and wavelength (lambda) illuminates the screen. The intensity of central maximum is I_0 . If the source were incoherent, the intensity at the same point will be :

Light from two coherent sources of same amplitude and same wavelength illuminates the screen. The intensity of the central maximum is I. If the sources were noncoherent, the intensity at the same point will be

Two coherent sources of equal intensity produce maximum intensity of 100 units at a point. If the intensity of one of the sources is reduced by 36% reducing its width, then the intensity of light at the same point will be

Two coherent sources of equal intensity produce maximum intensity of 100 units at a point. If the intensity of one of the sources is reduced by 36% reducing its width, then the intensity of light at the same point will be

In Young's double slit experiment, the two slits act as coherent sources of equal amplitude 'a' and of wavelength lambda . In another experiment with the same setup the two slits are sources of equal amplitude 'a' and wavelength lambda but are incoherent. The ratio of intensities of light at the mid point of the screen in the first case to that in the second case is ....
