In this experiment, the width of all the maximas are equal, all the maxima are of same intensity and the minima is almost zero that is completely dark pattern is obtained.
The conditions for the sustained interference are:The light used must be monochromatic.The source must produce constant light.The two sources must be coherent.The sources of light must be close to each other.The width of source must be very thin.Amplitudes must be equal for a good contrast.The separation between slit and the screen must be small.
