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)
6.2 Draw a labelled diagram to show the resultant pulse when the two pulses meet at point C. Label the pulses clearly. (2)
6.3 Name the type of interference that takes place when the pulses meet. (1)
6.4 Determine the resultant amplitude of the pulses at point C. (2)
6.5 How will the amplitude of pulse A be affected after passing point C? Write down only INCREASES, DECREASES or REMAINS THE SAME. (1)
