In Young's double slit experiment interference fringes `1^(@)` apart are produced on the screen, the slit separation is `(lambda = 589 nm)`

In Young's double slit experiment, the interference bright fringes are of:

In Young's double slit experiment what is the shape of interference fringes?

In a Young’s double slit experiment for interference of light, the slits are 0.2 cm apart and are illuminated by yellow light (lambda = 600 nm) . What would be the fringe width on a screen placed 1 m from the plane of slits if the whole system is immersed in water of index 4/3 ?

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

In Young 's double slit experiment the distance between the slits and the screen is doubled the separation between the slits is reduced to half. As a result the fringe width.

In Young's double slit experiment, the separation between the slits is halved and the distance between the slits and the screen is doubled. The fringe width is
