The maximum number of possible interference maxima for slit-separation equal to twice the wavelength in Young's double-slit experiment is

What type of interference pattern will be observed if two light sources of same wavelengths are used in Young's double-slit experiment ?

Question based on Interference and Young's Double Slit Experiment (YDSE)

The ratio of intensity at maxima and minima in the interference pattern is 25:9. What will be the widths of the two slits in Young's interference experiment ?

In a Young's double slit experiment if the slit separation is twice the wavelength of light used then the maximum number of interference maxima is

In Young'double-slit interference experiment, if the slit separation is made threefold, the fringe width becomes

Interference fringes in Young's double slit experiment with monochromatic light are

In Young's double slit interference experiment, the slit separation is made 3 fold. The fringe width becomes
