#P5.1a
describe wave motion in terms of amplitude, wavelength, frequency and period
#P5.1b
define wavelength and frequency
#P5.1c
describe and apply the relationship between wavelength, frequency and wave velocity
#P5.1d
apply formulae relating velocity, frequency and wavelength
#P5.1e
describe differences between transverse and longitudinal waves
direction of travel and direction of vibration
#P5.1f
show how changes, in velocity, frequency and wavelength, in transmission of sound waves from one medium to another, are inter-related
#P5.1g
describe the effects of reflection, transmission, and absorption of waves at material interface
examples such as ultrasound and sonar
#P5.1h
describe, with examples, processes which convert wave disturbances between sound waves and vibrations in solids
knowledge of a simple structure of the parts of the ear is expected
#P5.1i
explain why such processes only work over a limited frequency range, and the relevance of this to human hearing
why hearing (audition) changes due to ageing
#P5.1j
describe how ripples on water surfaces are used to model transverse waves whilst sound waves in air are longitudinal waves, and how the speed of each may be measured
#P5.1k
describe evidence for the cases of ripples on water surfaces and for sound waves in air that it is the wave that travels and not the water or the air
