K.C.S.E Physics Q & A - MODEL 1997PP2QN07

a) i. Distinguish between transverse and longitudinal waves
ii. Give one example of a transverse and one example of longitudinal.
b) Figure 6 shows the displacement of a particle in a progressive wave incident on a boundary between deep and shallow regions.

i. Complete the diagram to show what is observed after boundary. (assume no loss of energy)
ii. Explain the observation in (i) above.
(c) Water waves are observed as they pass a fixed point at a rate of 30 crests per minute. A particular wave crest takes 2s to travel between two fixed points 6m apart. Determine for the wave:
(a) The frequency 
(b) Wavelength 
(d) Figure 7 shows two loud speakers L1 and L2 connected to a signal generato
