Statement-1: if white light is used in YDSE, then the central bright fringe will be white. Statement-2: In case of white light used in YDSE all the wavelengths produce their zero order maxima at the same position.

The phase difference between light waves from two slits of Young's experiment is pi radian. Will the central fringe be bright or dark ?

Statement-1 : In Young’s experiment, the fringe width for dark fringes is same as that for white fringes. Statement-2 : In Young’s double slit experiment performed with a source of white light, only black and bright fringes are observed.

Statement-1 : When a white light passes through a prism it forms a spectrum of seven colours. Statement-2 : The refractive index for different colour of light is different for the material of prism.

Statement I : The fringe obtained at the centre of the screen in known as zeroth order fringe or central fringe. Statement II: Path difference between the waves from S_1 and S_2 reaching the centre is zero.

Statement-1: In YDSE central maxima means the maxima formed with zero optical path difference. It may be formed anywhere on the screen. Statement-2: In an interference pattern, whatever energy disappears at the minimum, appear at the maximum.

Statement I : White light gets dispersed when passed through a prism. Statement II: Different colours are deviated through different angles due to which white light splits.

Statement I: In Young's experiment, the fringe width for dark fringes is different from that of white fringes. Statement II: In Young's doulbe-slit experiment, when the fringes are observed with a source of white light then only black and bright fringes are observed.
