6.1 The figure below shows transverse wave motion. The period of the wave is
0,2 s.
Calculate the:
6.1.1 Frequency of the wave. (3)
6.1.2 Speed of the wave if distance D equals to 3 metres. (4)
Write down:
6.1.3 TWO pairs of points which are in phase. (2)
6.1.4 The amplitude of the wave motion (2)
6.2 Two pulses X and Y move towards each other at the same speed. The
amplitude of pulse X is 1,8 m and the amplitude of pulse Y is 1,2 m. The
pulses meet at point R.
6.2.1 Define a pulse. (2)
6.2.2 What is the name given to the type of interference that occurs at
point R? (1)
6.2.3 Draw the resultant of two pulses at point R.
(Indicate the resultant amplitude of the pulses in your diagram) (2)
