(a) describe what is meant by wave motion as illustrated by vibrations in ropes and springs and by
experiments using a ripple tank.
(b) state what is meant by the term wavefront.
(c) define the terms speed, frequency, wavelength and amplitude and do calculations using
velocity = frequency × wavelength.
(d) describe transverse and longitudinal waves in such a way as to illustrate the differences between them.
(e) describe the use of a ripple tank to show
(1) reflection at a plane surface,
(2) refraction due to a change of speed at constant frequency.
(f) describe simple experiments to show the reflection and refraction of sound waves.
hope it will help..
