Compare Young's Double slit interfemce pattern and single slit Diffraction pattern.

Explain Young's Double Slit Experiment.

Describe Young's double slit interference experiment and derive conditions for occurrence of dark and bright fringes on the screen. Define fringe width and derive a formula for it .

What must be the thickness of a thin film which, when kept near one of the slits shifts the central fringe by 5 mm for incident light of wavelength 5400 A^@ in Young's double slit intereference experiment? The refractive index of the material of the film is 1.1 and the distance between the slits is 0.5 mm.

In Young’s double-slit experiment, an interference pattern is obtained on a screen by a light of wavelength 6000overset@A , coming from the coherent sources S_1 and S_2 .At certain point P on the screen, third dark fringe is formed. Then the path difference S_1P-S_2P in microns is

In Young's double slit experiment using monochromatic light, the fringe pattern shifts by certain distance on the screen when mica sheet of refractive index 1.6 and thickness 1.964 microns is introduced in the path of one of the interfering waves. The mica sheet is then removed and the distance between the slits and screen is doubled. It is found that the distance between successive maxima now is same as the observed fringe shift upon the introduction of the mica sheet. Calculate the wavelength of the monochromatic light used in the experiment.

In a double slit experiment, the two slits are 1 mm apart and the screen is placed 1 m away. A monochromatic light of wavelength 500 nm is used. What will be the width of each slit for obtaining ten maxima of double slit within the central maxima of single slit pattern?

White light is used to illuminate the two slits in a Young's double slit experment . The separation between the slits is b and the screen is at a distance d ( d >> b ) from the slits . At a point on the screen directly in front of one of the slits , certain wavelengths are missing . Some of these missing wavelengths are

The angular width of the central maximum in a single slit diffraction pattern is 60^@ . The width of the slit is 1 mu m. The slit is illuminated by monochromatic plane waves. If another slit of same width is made near it, Young’s fringes can be observed on a screen placed at a distance 50 cm from the slits. If the observed fringe width is 1 cm, what is slit separation distance? (i.e., distance between the centres of each slit.)

In Young's double slit experiment the slits are 0.5 mm apart and interference is observed on a screen placed at a distance of 100 cm from the slits. It is found that the 9th bright fringe is at a distance 8.835 mm from the second dark fringe from the centre of the fringe pattern. Find the wavelength of light used.
