In a single slit diffraction experiment, the width of the slit is made double the original width. How does this affect the size and intensity of the central diffraction band?

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 a single slit diffraction pattern, the distance between the 1st minima on the right and the 1st minima on the left is 5.2 mm. The screen on which the pattern is displayed is 80 cm from the slit. If lambda= 5460 overset@A . Calculate the slit width.

In deriving the single slit diffraction pattern, it was stated that the intensity is zero at angles of n lambda/a .Justify this by suitably dividing the slit to bring out the cancellation .

Two slits in Young Experiment have width in the ratio 81:1 . What is the ratio of the amplitudes of the waves coming from them.

In Young's experiment, the pinholes are illuminated, by a monochromatic light of wavelength 5200 overset (@)(A) . A screen is placed at 1 m from the slit. If the pinholes are 1.3 mm apart, find i)fringe width ii) the distance between the seventh bright band on one side and sixth dark band on the other side of the central bright band.

Zener diodes have higher dopant densities as compared to ordinary p- n junction diodes. How does it affect the width of depletion layer

What must be the ratio of slit width on the wavelength for a single slit to have the firust diffraction minimum at 45^@ .

In a biprism experiment , the band width is found to be increased by 25% of the initial . If the distance between slit and eyepiece is increased by 20 cm then the initial distance between slit and eyepiece is

In a biprism experiment , the slit is illuminated by a light of wavelength of 5000 overset (@)(A) . The distance between the slit and eyepiece is 1 m . If the distance between the two virtual sources is 0.25 cm , then distance between fifth bright band on one side and the sixth dark band on the other sideof the central bright band will be
