Exam questions on Properties of waves

1. A cork floats on the surface of a pond in Kerala. A stone is dropped into the pond and ripples spread outwards. As the ripples pass, the cork bobs up and down but stays in about the same place.
   State how the direction of the vibrations differs between transverse and longitudinal waves, and give one example of each type.2 marks
2. A wave machine in a swimming pool in Singapore produces regular water waves with a frequency of 0.50 Hz and a wavelength of 3.0 m.
   The wave speed in the pool stays at 1.5 m/s. The frequency of the wave machine is increased to 1.0 Hz. Calculate the new wavelength.2 marks
3. A student uses a ripple tank to measure the speed of water waves. A motor makes a straight bar dip into the water 8.0 times each second, which produces a train of waves. The student holds a ruler beside the pattern and measures a distance of 12.5 cm across 5 complete wavelengths.
   Calculate the wavelength and the speed of the water waves.3 marks
