Explain two features to distinguish between the interference pattern in Young's double slit experiment with the diffraction pattern obtained due to a single slit.

Answer

Interference pattern	Diffraction pattern
1) All fringes are of equal width.	1) The width of central maxima is twice the width of higher order band.
2) Intensity of all bright bands is equal.	2) The intensity goes on decreasing for a higher order of diffraction bands.
