A cyclist is using a loudspeaker to measure her speed. She cycles directly towards the loudspeaker which emits a sound with a constant frequency 261 Hz. The cyclist measures the frequency to be 269 Hz. You should assume that the speed of sound in air is 335 m s-¹. (a) Calculate the speed of the cyclist. (b) Describe briefly what the cyclist will hear as she passes the loudspeaker.

Seiche
A seiche is an oscillating standing wave in a body of water. The term seiche pronounced saysh) can be understood by the sloshing of water back and forth in a swimming pool. The same phenomenon happens on a much larger scale in vast bodies of water including bays and lakes. A seizure can happen in any enclosed or semi-enclosed body of water.
