4. Question 6.1 · November 2017 · Paper 1 · National (DBE) · 3 marks
Two girls, standing at opposite ends of a rope, each makes a pulse of the same speed. Pulse A, with an amplitude of $4$ cm, moves to the right and pulse B, with an amplitude of $- 6$ cm, moves to the left. The pulses meet at point C.
6.1 State the phenomenon observed when the two pulses meet at point C.(3)

Four options are provided as possible answers to the following questions. Each question has only ONE correct answer. Choose the answer and write only the letter (A–D) next to the question number (1.1–1.5) in the ANSWER BOOK, for example 1.6 E.
1.1 Pulse A, moving to the right, with an amplitude of Y metres overlaps with Pulse B, moving to the left, with an amplitude of ½ Y metres, as shown in the diagram below.

Which of the following combinations will be CORRECT when the pulses meet at the same point in the medium?(2)
1. A Type of interference: Constructive; Amplitude: $1, 5 Y$
2. B Type of interference: Destructive; Amplitude: $1, 5 Y$
3. C Type of interference: Constructive; Amplitude: $0, 5 Y$
4. D Type of interference: Destructive; Amplitude: $0, 5 Y$

  Correct optionPulse A is a crest (upwards) and pulse B is a trough (downwards), so when they meet they cancel partly: this is destructive interference.
  The resultant amplitude is the difference of the two amplitudes: $Y - \frac{1}{2} Y = 0, 5 Y$ .
