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-

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's 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 7500 A^(@) and 5000 A^(@) , the value of 'n' is

In young's 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 7500 A^(@) and 5000 A^(@) , the value of 'n' is

The distance of n^(th) bright fringe from the centre of the interference pattern is

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 the interference pattern obtained in a biprism experiment, 5th order bright fringe is obtained at a point on the screen, when monochromatic light of wavelength 6000 Å is used. What is the order of the bright fringe produced at the samme point, if the light of wavelength 5000 Å is used?

An interference pattern was made by using red light. If the red light changes with blue light, the fringes will become
