Monochromatic light of `lamba=5000Å` is incident on two slits separately by a distance of `5xx10^(-4)m`. The interference patteren is seen on a screen placed at a distance of 1m form the slits. A thing glass plate of thicknes `1.5xx10^(-6)m` and refractive index `mu=1.5` is placed between one of the slits and the screen. Find the intensity at the centre of the screen if the density there is `I_(0)` in the absence of the plate. Also find the lateral shift of the central maximum. '

A monochromatic light of lambda=500 nm is incident on two identical slits separated by a distance of 5xx10^(-4)m . The interference pattern is seen on a screen placed at a distance of 1 m from the plane of slits. A thin glass plate of thickness 1.5xx10^(-6)m and refractive index mu=1.5 is placed between one of the slits and the screen. Find the intensity at the centre of the screen if the intensity is I_(0) in the absence of the plate. Also find the lateral shift of the central maxima and number of fringes crossed through centre.

A monochromatic light of lambda = 500 Å is incident on two indentical slits separated by a distance of 5 xx 10^(-4) m. The interference pattern is seen on a screen placed at a distance of 1 m from the plane of slits. A thin glass plate of thickness 1.5 xx 10^(-6) m and refractive index mu = 1.5 is placed between one of the slits and the screen . Find the intensity at the center of the screen.

A monochromatic light of lambda=5000Å is inciden on two slits seperated by a distance of 5xx10^(-4)m. if a thin glass of thickness 1.5xx10^(-6) m and refractive index 1.5 placed between one of the slits and screen. The pahses difference introduced at the position of central maxima is

Light d of wavelength 5000Å is incident normally on a slite. The first minimum of the distance of 5 mm from the central maximum on a screen placed at a distance of 2 m from the slit. The width of slit is

A thin glass plate of thickness is (2500)/3lamda ( lamda is wavelength of light used) and refractive index mu=1.5 is inserted between one of the slits and the screen in Young's double slit experiment. At a point on the screen equidistant from the slits, the ratio of the intensities before and after the introduction of the glass plate is :

Two slits at a distance of 1mm are illuminated by a light of wavelength 6.5xx10^-7m . The interference fringes are observed on a screen placed at a distance of 1m . The distance between third dark fringe and fifth bright fringe will be

Light of wavelength 5000 Å is incident on a double with and the interference fringes are formed on a screen plated at a distance of 1m from the slits. If the distance between the two consecutive dark bands is 1 mm, then the distance between the two slits is

In Yonung's double-slit experiment, two slits which are separated by 1.2 mm are illuminated with a monochromatic light of wavelength 6000 Å The interference pattern is observed on a screen placed at a distance of 1 m from the slits. Find the number of bright fringes formed over 1 cm width on the screen.
