In young double slit experiment the `n^(th)` red bright band coincides with `(n+1)^(th)` blue bright band.If the wavelength of red and blue lights are `7500A^(@)` and `5000A^(@)` ,the value of `n` is

In young double slit experiment the ratio of intentsities of bright and dark bands is 16 which means

In Young's double slit experiment, if the source of light changes from orange to blue then :

In young's double slit experiment, the distance of the n-th dark fringe from the centre is

In an interference pattern the (n+4)^(th) blue bright fringe and n^(th) red bright fringe are formed at the same spot. If red and blue light have the wavelength of 7800Å and 5200 Å then value of n should be-

Then nth bright band of red light of wavelength 6750Å is coincide with (n+1)^(th) bright band of green light of wavelength 5400Å . Find the value of n .

In Young's double slit experiment, if the width of 4th bright firnge is 2xx10^(-2) cm then the width of 6 th bright fringe will be cm

In a biprism experiment, if the width of the fourth bright bannd is 1mm, then the width of the 8th bright band will be

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
