Show that the superposition of the waves originating from the two coherent sources `S_1` and `S_2` having displacements
`y_1=a cos omega t and y_2 = cos (omega t + phi)`.at a point produce a result intensity `I_(R)=4a^(2)"cos"^(2)(phi)/(2)`.
Hence,write the conditions for the appearance of bringt and dark fringes.
