A source of sound of frequency 1000 Hz moves to the right with a speed of 32(m)/(s) relative to the ground. To its right there is a reflecting surface moving to the left with a speed of 64(m)/(s) relative to the ground. Take the speed of 64(m)/(s) . Relative to the ground. Take the speed of sound in air to be 332(m)/(s) and find (a) The wavelength of the sound emitted in air by the source, (b) the number of waves per second arriving at the reflecting surface, (c ) The speed of the reflected waves and (d) The wavelength of the reflected waves.

A sounding fork whose frequency is 256 Hz is held over an empty measuring cylinder. The sound is faint , but if just the right amount of water is poured into the cyclinder , it becomes loud. If the optimal amount of water produce an air column of length 0.31 m , then the speed of sound in air to a first approximation is
