Question

What will happen to diffraction pattern of single slit be affected when width of slit is decreased?

Answer 1

Answer:

(a) In a single slit diffraction experiment, if the width of the slit is made double the original width, then the size of the central diffraction band reduces to half and the intensity of the central diffraction band increases up to four times. ... Thus, the diffraction angle will be very small.

Answer 2

Answer:

(i)When the slit width is decreased width of the fringes will incease. (ii)When monochromatic source is replaced by white light coloured fringes will be observed.
