Why can we not get diffraction pattern from a wide slit illuminated by monochromatic light ?

Statement I : We cannot get diffraction pattern from a wide slit illuminated by monochromatic light. Statement II: In diffraction pattern all the bright bands are not of the same intensity.

Why can we not get diffraction from a wide slit illuminated by a monochromatic light?

Assertion (A) : We cannot observe diffraction pattern from a wide slit illuminated by monochromatic light Reason (R ) : In diffraction pattern, all the bright bands arenot of the same intensity.

Give reasons : (a) Diffraction of sound waves is easier to observe than light waves. (ii) We do not observe diffraction from wide slit illuminated with monochromatic light.

Draw the diffraction pattern due to a single slit by a monochromatic light.

Use Huygens's principle to explain the formation of diffraction pattern due to a single slit illuminated by a monochromatic source of light. When the width of the slit is made double the original width, how would this affect the size and intensity of the central diffraction band ?

Discuss the diffraction produced by a narrow slit which is illuminated by a monochromatic light.

What two main changes in diffraction pattern of a single slit will you observe, when the monochromatic source of light replaced by a source of white light
