Year 12 Physics – Term 2 Week 5 Review #1
1. Describe the difference between Transverse and Longitudinal
(Compression Waves)
2. Draw a transverse wave with wavelength 4cm and amplitude 2cm. Draw
any two points A and B on the wave showing them ‘in phase’ and points C
and D showing them ‘out of phase ‘
3. Experimental evidence shows that successive compressions of a sound
wave in water are 5metre apart. If the frequency of the wave is 500Hz,
what is the speed of the wave in water?
4. a) Draw a diagram that depicts a single wave pulse travelling from a less
dense to a more dense medium, before and after interaction with the
medium boundary.
b) Discuss and compare how any of the wave properties are effected and
state the wave properties involved.
5. a) Draw a diagram (from above) of a wave traveling at 2.5m/s form a
deep to a shallow region where the velocity reduces to 1.5m/s.
b) If the incident wave has a wavelength of 2cm, calculate the wavelength
in the shallow region
c) Discuss the property being demonstrated in this question and calculate
the frequency of the wave.
6. a) Draw a diagram of a standing wave produced in an extended spring
where there are 4 nodes present along the waveform.
b) Explain how the wave is formed in the spring and how the nodes are
formed
c) If the distance between successive nodes is 1.0metres and the
frequency of vibration is 4Hz. What is the velocity of the wave and which
standing wave harmonic is being demonstrated?
