In the Young's double slit experiment, if the phase difference between the two waves interfering at a point is f, the intensity at that point can be expressed by the expression [MP PET 1998; MP PMT 2003]

\[I=\sqrt{{{A}^{2}}+{{B}^{2}}{{\cos }^{2}}\varphi }\]

\[I=A+B\cos \varphi \] Where A and B depend upon the amplitudes of the two waves.
