In Fraumhroffer diffraction pattern due to a single slit, the screen is at distance of 100 cm from the slit and slit is illuminated by `lambda=5893Å`. The width of the slit is 0.1 mm. Then separation between central maxima and the first secondary minima

A light of wavelength 6000Å is incident on a single slit . First minimum is obtained at a distance of 0.4 cm from the centre . If width of the slit is 0.3 mm, the distance between slit and screen will be

A light of wavelength 6000Å is incident on a single slit . First minimum is obtained at a distance of 0.4 cm from the centre . If width of the slit is 0.3 mm, the distance between slit and screen will be

In a single slit diffraction pattern the angular width of a central maxima is 30^(@) . When the slit is illuminated by light of wavelength 6000Å . Then width of the slit will be approximately given as :

In a single slit diffraction set-up, the screen is placed at a distance of 80 cm from a slit. Light of 5,000 Å is illuminated on the slit, the diffraction pattern is oberved on the screen. Determine the aperture of the slit if distance between first and second minima is 2.1 mm.

In the diffraction pattern due to a single slit linear width of the central max will be twice that of slit width (d) . The distance between the slit and the screen is

First secondary minima in case of diffraction due to single slit is obtained at a distance x from central maximum position, then

A screen is placed at 50cm from a single slit, which is illuminated with 600nm light. If separation between the first and third minima in the diffraction pattern is 3.0mm , then width of the slit is:

A screen is placed at 50cm from a single slit, which is illuminated with 600nm light. If separation between the first and third minima in the diffraction pattern is 3.0mm , then width of the slit is:

In Fraunhoffer diffraction by a single slit, the width of the slit is 0.01 cm. If the wavelength of the light incident normally on the slit is 5000 Å the angular distance of second maxima from the mid line of central maxima is ...... rad.
