In Young's double -slit experiment, why do we use mono chromatic light ? If while light is used, how would the pattern change ?

In Young's double slit experiment if monochromatic light is replaced by white light

In Young's double slit experiment if monochromatic light is replaced by white light

In Young's double slit experiment if monochromatic light is replaced by white light

In a Young's double-slit experiment apparatus, we use white light. Then

In a Young's double slit experiment, (slit distance d) monochromatic light of wavelength lambda is used and the fringe pattern observed at a distance D from the slits. The angular position of the bright fringes are

In Young's double slit experiment light waves are coherent. Why?

In a Young's double slit experiment (slit distance d) monochromatic light of wavelength lambda is used and the figure pattern observed at a distance L from the slits. The angular position of the bright fringes are
