A screen is placed 40 cm from a narrow slit. Parallel light rays of wavelength 5890 Å fall on the slit. First minimum is formed 2 mm on either side of central maximum.Find the width of the narrow slit.

For producing a fraunhofer diffraction fringe, a screen is placed 2m away from a single narrow slit. If the width of slit is 0.2 mm, it is found that first minimum lies 5 mm on either side of the central maximum. Find the wavelength of the incident light.

A screen is placed 2m away from the single narrow slit. Calculate the slit width if the first minimum lies 5 mm on either side of the central maximum. Incident plane waves have a wavelength of 5000 Å .

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.

Light of wavelength 6 xx10^(-5) cm falls on screen at a distance of 100 cm from a narrow slit. Find the width of the slit if the first minima lies 1mm on either side of the central maximum
