In a Young's double slit experiment using red and blue lights of wavelengths 600 nm and 480 nm respectively, the value of n for which the nth red fringe coincides with `(n+1)` th blue fringe is

In Young's double slit experiment, the wavelength of red light is 5200 Å . The value of n for which nth bright band due to red light coincides with (n+1)th bright band due to blue light, is

In Young's double slit experiment, the wavelength of red light is 7800 Å . The value of n for which nth bright band due to red light coincides with (n+1)th bright band due to blue light (lambda=5200Angstrom) , is

In young's double slit experiment 'the wavelength of red light is 7800Å and that of blur light is 5200Å .the value of n of which nth bright band due to red light coincides with (n+1)bright band due to blue light is:

Interference fringes are obtained in a Young's double slit experiment using beam of light consisting two wavelengths 500 nm and 600 nm. Bright fringes due to both wavelengths coincide at 2.5 mm from the central maximum. If the separation between the slits is 3 mm, then the distance between the screen and plane of the slits is

A Young's double slit experiment is performed with blue (wavelength 460 nm) and green light (wavelength 550 nm) respectively. If y is the distance of 4th maximum from the central fringe then
