    Progressive waves are represented by the equation   \[{{y}_{1}}=a\,\sin \,(\omega t-x)\] and        \[{{y}_{2}}=b\,\cos \,(\omega t-x)\]       The phase difference between waves is:

    A)  \[0{}^\circ \]                                     

    B)  \[45{}^\circ \]                  

    C)         \[90{}^\circ \]                  

    D)         \[180{}^\circ \]

    Correct Answer: C

    Solution :

    As it is dear that the phase difference between \[\cos \theta \] and \[sin\,\theta \] representing two simple harmonic motion is\[90{}^\circ \].
