A parallel beam of light of wavelength 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. Find the width of the slit

Light of wavelength 6000 overset (@)(A) is incident normally on a slit . The first minimum in the diffraction pattern is observed to be at a distance of 6 mm from the central maximum on a screen , which is at a distance of 2 m from the slit . Calculate the width of the 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.

Monochromatic electromagnetic radiation with wavelength from a distant source passes through a slit. The diffraction pattern is observed on a screen 2.50 m from the slit. If the width of the central maximum is 6.00 mm, what is the slit width if the wavelength is (a) 500 nm (visible light); (b) 50.0 um (infrared radiation); (c) 0.500 nm (x rays)?

A parallel beam of green light of wavelength 546 nm passes through a slit of width 0.4 mm. The intensity pattern of the transmitted light is seen on a screen which is 40 cm away. What is the distance between the two first order of minima?

In Fraunhaffer diffraction by a narrow slit, a screen is placed, at a distance of 2 m, from the lens to obtain a diffraction pattern. If the slit width is 0.2 mm and the first minimum is 5 mm, on either side of the central maximum. Find the wavelength of light.
