Light of wavelength 6328 Å is incident normally on a slit of width 0.2 mm. Calculate the angular width of central maximum on a screen distance 9 m?

Light of wavelength 6328 Å is incident normally on a slit of width 0.2 mm. Calculate the angular width of central maximum on a screen distance 9 m?

What will be the angular width of central maxima in Fraunhofer diffraction when light of wavelength 6000Å is used and slit width is 12xx10^-5cm ?

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 :

Calculate the width of central maxima, if light of 9000Å incidents upon a slit of width 1.5 mm. Screen is kept 150 cm away from the slit.

A slit of worth 12 times 10^-7 m is illuminated by light of wavelength 6000A. The angular width of the central maximum is approximately-
