Whether the diffraction effects from a slit will be more clearly visible or less clearly, if the slit-width is increased ?

Proportion of diffraction by slit .......

The fraunhofer diffraction pattern of a single slit is formed at the focal plane of a lens of focal length 1m. The width of the slit is 0.3 mm. if the third minimum is formed at a distance of 5 mm from the central maximum then calculate the wavelength of light.

In a fraunhofer's diffraction by a slit, if slit width is a, wave length lamda focal length of lens is f, linear width of central maxima is-

In Fraunhoffer diffraction, the wavelength incident light perpendicular to slit made double. the distance from the slit to the screen made tripled and if the width of the slit made (3)/(2) times then width of central maximum will be.....

If I_0 is the intensity of the principal maximum in the single slit diffraction pattern. Then what will be its intensity when the slit width is doubled?

In the diffraction pattern of a single slit aperture, the width of the central fringe compared to widths of te other fringes is-

In a single slit diffraction pattern, if the light source is used of less wave length then previous one. Then width of the central fringe will be-
