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

Draw the well labelled diagram of diffraction of light at a single slit .

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)?

What is the condition for first minima in case of diffraction due to a single slit ?

In the diffraction pattern due to a single slit of width 'd' with incident light of wavelength 'lambda' , at an angle of diffraction 'theta' , the condition for first minimum is

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?

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

A lens of focal length f gives diffraction pattern of Fraunhoffer type of a slit having width a. If wavelength of light is lambda , the distance of first dark band and next bright band from axis is given by

a double - slit arrangement, the slits are separated by a distance equals to 100 times the wavelength of light passing through the slits:- What is the angular separation in radians between the central maximum and an adjacent maximum?
