The frequency of the wave is (a) 0.5 Hz (b) 1.0 Hz (c) 1.5 HZ (d) 2.0 Hz 4. A boy fishing on the jetty observes water waves coming in from the ocean. He sees one wave pass him by every two seconds, each with a wavelength of 0.5 m. The speed of the waves is (a) 0.25 ms- (b) 0.5 ms -1 (c) 1.0 ms -1 (d) 2.0 ms -1 Continued overleaf 49 5. The figure below shows two wave pulses that are approaching each other. P Which of the following best shows the shape of the resultant pulse when the centres of the pulses, points P and Q, coincide? (A) (B) (C) (D) (E) 1-" 6. A standing wave of frequency 5 Hz is set up on a string 2 m long with nodes at both ends and in the centre, as shown. 2 m The speed at which waves propagate on the string is (a) 1.0 ms -1 (b) 2.5 ms -1 (c) 5.0 ms -1 (d) 10 ms -1 (e) 20 m - 1
