UCT ONLINE HIGH SCHOOL 10/16 QUESTION 2 [15 marks] PHYSICAL SCIENCES Two Physical Sciences students are attending a soccer match at FNB stadium when the fans on the opposite side of the stadium start a Mexican wave. A Mexican wave is produced when a group of fans stand up and sit down. As they sit down the group next to them stands up and sits down and so the "wave" is transmitted around the stadium. https://nature.berkeley.edu/garbelottoat/?p=824 Figure 5: Wave representation of a Mexican wave. Question 2.1.1 [2 mark] Define a transverse wave. Question 2.1.2 [2 mark] Explain why a Mexican wave is an example of a transverse wave. Question 2.1.3 [3 mark] One student records that it takes the wave 2 minutes to pass around the entire stadium. If the circumference of the stadium is 535 m, calculate the speed of the Mexican wave. ©2019 Valenture Institute All Rights Reserved (not authorised for commercial use) UCT ONLINE HIGH SCHOOL PHYSICAL SCIENCES Question 2.1.4 [1 mark] Suggest what motion the fans would have to make to produce a longitudinal wave. Question 2.1.5 [1 mark] Another wave is started at the opposite side of the stadium. The amplitudes of the pulses (pulse x and pulse y) are on opposite sides of the equilibrium/rest position. Write a mathematical equation in terms of the two amplitudes (y and x) to express how they would interfere when they meet.
