A long narrow slit is illuminated by blue light and the diffraction pattern is obtained on a white screen:-What do you mean by limit of resolution of an optical instrument?

A long narrow slit is illuminated by blue fight and the diffraction pattern is obtained on a white screen:-What happens to the width of patten, if yellow fight is used instead of blue light?

A long narrow slit is illuminated by blue light and the diffraction pattern is obtained on a white screen:-How the width of bands change as the distance from the centre increases?

A long narrow slit is illuminated by blue light and the diffraction pattern is obtained on a white screen:-In a double slit experiment, the slits are separated by 0.03 cm and the screen is placed 1.5 m away. The distance between the central fringe and the fourth bright is 1 cm. Determine the wavelength of light used in the experiment.
