In a double slit or a biprism experiment, the fringe width for red colour as compared to that for violet colour is approximately

In Youngs double slit experiment, to increase the fringe width

In Young.s double slit experiment the band width is minimum for the colour

A : In Young.s double slit expriment the band width for red colour is more R : Wavelength of red is small among the colours of white light.

Assertion (A) : In Young's double slit experiment the band width for red colour is more Reason (R ): Wavelength of red is small
