Phase Difference ?

The figure shows two point sources of light, A and B. B emits light waves that are +p radians out of phase with the waves from A. A is 3λ from P. B is 5λ from P. (λ is the wavelength.) What is the phase difference between waves arriving at P from A and B?

    If the phase difference was zero, these waves would be in phase. So the phase difference at P must be +p radians.
