            speed  of  the  wave  and  its  fundamental                ω       k
            frequency is                                            A.   A    B.   A     C. KA   D. ωA

            A. 180 m/s, 80 Hz  B. 320 m/s, 80 Hz
            C. 320 m/s, 120 Hz  D. 180 m/s, 120 Hz

        24.Velocity  of  sound  wave  in  air  is  330  m/s.
            For  a  particular  sound  wave  in  air,  a  path
            difference of 40 cm is equivalent to phase
            diff of 1.6π . The frequency of this wave is

            A. 165 Hz  B. 150 Hz  C. 660 Hz
            D. 330 Hz

        25.y = A sin(ωt − kn)      .    What       is    the
            magnitude of slope of the curve at B?
