Why are parallel slits preferable to the pin holes that Young used in demonstrating interference?

(i) In Young's double slit experiment the condition for (a) constructive and (b ) destructive interference at a point on the screen .

In Young’s double slit experiment, the intensity of light coming from the first slit is double the intensity from the second slit. The ratio of the maximum intensity to the minimum intensity on the interference fringe pattern observed is

The width of one of the two slits in a Young's double slit experiment is double of the other slit. Assuming that the amplitude of the light coming from a slit is proportional to the slit width, find the ratio of the maximum to the minimum intensity in the interference pattern.

The width of one of the two slits in a Young's double slit experiment is double of the other slit. Assuming that the amplitude of the light coming from a slit is proportional to the slit width, find the ratio of the maximum to the minimum intensity in the interference pattern.

The intensity of the light coming from one of the slits in a Young's double slit experiment is double the intensity from the other slit. Find the ratio of the maximum intensity to the minimum intensity in the interference fringe pattern observed.

Monochromatic light from a narrow slit illuminates two parallel slits producing an interference pattern on a screen. The separation between the two slits is now doubled and the distance between the screen and the slits is reduced to half. The fringe width

State the importance of coherent sources in the phenomenon of interference. In Young's double slit expet-ment to produce interference pattern obtain the conditions for constructive and destructive interference. Hence deduce the expression for the fringe width. How does the firinge width get affected, if the entire experimental apparatus of Young's is immersed in water ?

The intensity of light emerging from one slit is nine times than that from the other slit in Young's double sit interference set up. The ratio of maximum intensity to minimum intensity in the fringe pattern is

In Young's double slit experiment, if the two slits are illuminated with separate sources, no interference pattern is observed because

What should be the path difference between two waves reaching a point for obtaining constructive interference in Young.s Double Slit experiment?
