Light of wavelength 5000 Å, illuminates the slit in a biprism experiment. If it is replaced by light of wavelength 6500 Å, then the fringe width will

If in a biprism experiment, light of wavelength 5000 Å is replaced by 10,000 Å, then the fringes will

In a certain double slit experimental arrangement interference fringes of width 1.0mm each are observed when light of wavelength 5000Å is used. Keeping the set up unaltered, if the source is replaced by another source of wavelength 6000Å , the fringe width will be

In a certain double slit experimental arrangement interference fringes of width 1.0mm each are observed when light of wavelength 5000Å is used. Keeping the set up unaltered, if the source is replaced by another source of wavelength 6000Å , the fringe width will be

The fringe width in a biprims experiment is 0.32 mm, when red light of waelength 6400Å is used. If source of blue light of wavelength 4000Å is used with the same setting, then the fringe width will
