A light of `5000overset@A` is incident on the double slit and a fringe is observed on a screen 2m apart of fringe width 0.16mm. What is the slit width?

What are coherent sources ? Green light of wavelength 5100 Å is incident on a double slit. If the overall separation of 10 fringes on a screen 200 cm away from the slits is 2 cm find the distance between the slits.

A parallel beam of light of 500 nm falls on a narrow slit and the resulting diffraction pattern is observed on a screen 1 m away. It is observed that the first minimum is at a distance of 2.5 mm from the centre of the screen. Calculate the width of the slit.

Green light of wavelength 5100 A from a narrow slit is incident on a double slit. If the overall separation of 10 fringes on a screen 200 cm away is 2 cm find the separation between the slits.

In Young's double Slit experiment the two slits are d distances apart.Interference pattern is observed on a screen at a distance D from the slits . A dark frings is observed on the screen directly opposite to one of the slits. The wavelength of lights is

A light of wavelength lambda falls on a narrow slit of width d.A diffraction fringe is formed on a screen placed at distance D from the slit. If the linear width of the central maximum equals to the width of the slit, will be the value of D?

A beam of light of lambda = 600 nm from a distant source falls on a single slit 1 mm wide and the resulting diffraction pattern is observed on a screen 2 m away. The distance between first dark fringes on either side of the central bright fringe is

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)

The width of single slit diffraction fringes varies
