In Young's double slit experiment describe briefly how bright and dark fringes are obtained on the screen kept in front of a double slit. Hence obtain the expression for the fringe width.

In Young's double slit experiment the ratio of intensities of bright and dark fringes is 9. This means

If young' s double slit experiment is performed using white light, then

In Young's double slit experiment the coherent sources are 1.5 mm apart and the fringes are obtained on a screen at a distance 2.5 m from the plane of the sources. If the sources is illuminated with a light of 589.3 nm wavelength , find the number of fringes in the interference pattern thus formed on the screen. Total length of the fringes are 4.9 xx 10 ^(-3) m.

If a Young's double slit experiment were conducted inside water instead of air, the fringe width would

In Young's double slit experiment what is the path difference between the two light waves forming 5th bright band on the screen ?

If Young's double slit experiment is performed by using a source of white light then bright and dark fringe pattern is seen. Is the statement true or false ?

In Young's double slit experiment the width of the fringe is 2.0 mm. Find the distance between 9th bright band and 2nd dark band.
