A wave on a lake has a cycle length of 0.620 m anda period of 0.300 s. What is the speed of the wave?

22 A transverse water wave is moving along the surface of some water. This causes a ball to movevertically without moving horizontally as it floats upon the surface. At one instant, the ball is at theposition shown.2.4 m0.70 mballdirection ofwave travelNOT TOSCALEThe wave has a frequency of 0.20 Hz and an amplitude of 0.70 m. The distance between a troughand an adjacent peak is 2.4 m.What is the distance travelled by the ball in a time of 20 s?A 5.6 m B 9.6 m C 11.2 m D 19.2 m23 A sound wave travels from left to right across a room. The variation with distance across theroom of the displacement of the air molecules at one instant is shown.At which distance will the air pressure be lowest?displacementdistance from left-handend of roomrightleft0A B C D24 A source emits a sound wave of a single frequency. The Doppler effect causes a differentfrequency of sound to be heard by a stationary observer.What is a requirement for the Doppler effect to occur?A a source that is moving as it produces the sound waveB a source that produces a polarised sound waveC a source that produces a sound wave of changing amplitudeD a source that produces a sound wave of changing frequency

A ship anchored in a port has a ladder which hangs over the side. The length of the ladder is 200cm, the distance between each rung in 20cm and the bottom rung touches the water. The tide rises at a rate of 10cm an hour. When will the water reach the fifth rung?

Which two waves, with the properties listed below, travel at the same speed?(Select two answers below)Group of answer choiceswavelength = 3m, frequency = 6 cycles/swavelength = 5m, frequency = 3 cycles/swavelength = 3m, frequency = 4 cycles/swavelength = 4m, frequency = 4 cycles/swavelength = 4m, frequency = 5 cycles/swavelength = 2m, frequency = 6 cycles/swavelength = 5m, frequency = 5 cycles/s
