#P1.3.1
describe wave motion in terms of amplitude, wavelength, frequency and period
#P1.3.2
describe evidence that for both ripples on water surfaces and sound waves in air, it is the wave and not the water or air itself that travels
#P1.3.3
describe the difference between transverse and longitudinal waves
#P1.3.4
describe how waves on a rope are an example of transverse waves whilst sound waves in air are longitudinal waves
#P1.3.5
define wavelength and frequency
#P1.3.6
recall and apply the relationship between speed, frequency and wavelength to waves, including waves on water, sound waves and across the electromagnetic spectrum:
wave speed (m/s) = frequency (Hz) × wavelength (m)
#P1.3.7
a) describe how the speed of ripples on water surfaces and the speed of sound waves in air may be measured
b) describe how to use a ripple tank to measure the speed/frequency and wavelength of a wave
PAG4
#P1.3.8
a) describe the effects of reflection and refraction of waves at material interfaces
b) describe how to measure the refraction of light through a prism
PAG8
c) describe how to investigate the reflection of light off a plane mirror
PAG8
#P1.3.9
recall that waves travel in different substances at different speeds and that these speeds may vary with wavelength
#P1.3.10
explain how refraction is related to differences in the speed of the waves in different substances
#P1.3.11
recall that light is an electromagnetic wave
#P1.3.12
recall that electromagnetic waves are transverse
