If an interfernce pattern,at a point we observe the `16^(th)` order maximum for `lambda_(1)=6000Å`. what order will be visible here if the soruce is replaced by light of wavelength `lambda_(2)=4800Å`

In a Young's double slit interference pattern at a point , we observe the 10th bright fringe (order maxima) for wavelength 7000 Å . What order maxima will be visible if the source of light is replaced by light of wavelength 5000 Å?

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 young's slit experiment 10thorder maximum is obtained at the point of observation in the interference pattern for lambda=7000Å .If the source is replaced by another one of wavelength 5000Å then the order of maximum at the same point will be-

In Young's double slit experiment, red light of wavelength of 6000Å is used and the n^(th) bright fringe is obtained at a ponit P on the screen. Keeping the same setting, the source of light is replaced by green light of wavelength 5000Å and now (n+1)^(th) bright fringe is obtained at the point P on the screen. The value of n is

If an interference experiment is performed using two wavelengths close to each other, two interference patterns corresponding to the two wavelengths are obtained on the screen. The frings system remains distinct up to a point on the screen where the n^("th") order maximum of one wavelength falls on the n^("th") order minimum of the other wavelength. Suppose in Young's double sit experiment, sodium light composed of two wavelengths lambda_(1)and lambda_(2) close to each other (with lambda_(2) greater than lambda_(1) ) is used. The order n, up to which the fringes can be seen on the screen, is given by

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?

In young’s double slit experiment, when the slit plane is illuminated with light of wavelength lambda_(1) , it was observed that point P is closest point from central maximum O, where intensity was 75% the intensity at O. When the light of wavelength lambda_(2) is used, point P happens to be the nearest point from O where intensity is 50% of that at O. Find the ratio (lambda_(1))/(lambda_(2)) .

The ratio of resolving power of an optical microscope for two wavelength lambda_(1)=4000Å and lambda_(2)=6000Å is:
