    The equation of the propagating wave is  \[y=25\sin (20t+5x),\] where \[y\] is displacement. Which of the following statement is not true                           [MP PET 2003]

    A)            The amplitude of the wave is 25 units

    B)            The wave is propagating in positive \[x\]-direction

    C)            The velocity of the wave is 4 units

    D)            The maximum velocity of the particles is 500 units

    Correct Answer: B

    Solution :

               Positive sign in the argument of sin indicating that wave is travelling in negative x-direction.
