Properties of Waves (cont’d)

Students should be able to:

2.7. use the terms phase, and
phase difference with
reference to behaviour of
waves;

2.8. distinguish between Explanation of nodes and
stationary and progressive anti-nodes.
waves;

2.9. explain the properties of For example, microwaves, See Appendix II for
stationary waves and waves on strings, closed suggested practical activity.
perform related and open pipes (include
calculations; resonance tube).

2.10. describe practical Use of sonar waves in
applications of sound determining the depth of
waves in industry; the sea, and in medicine,
such as in foetal imaging.

2.11. discuss application of Include percussion
sound waves to musical instruments such as the
instruments; steel pan; stringed
instruments such as the
guitar; and wind
instruments such as the
flute.

2.12. apply the laws of reflection
and refraction to the
behaviour of waves;

2.13. describe experiments to Use a ripple tank together
demonstrate diffraction of with both narrow and wide
waves in both narrow and gaps, microwaves, lasers.
wide gaps; Use virtual labs to
demonstrate diffraction.

2.14. explain the meaning of
coherence as applied to
waves;
