(d) show an understanding that energy is transferred due to a progressive wave.
(f) show an understanding of and apply the concept that wave from a point source and travelling without loss of energy obeys an inverse square law to solve problems.
Transverse and Longitudinal Waves
(g) analyse and interpret graphical representations of transverse and longitudinal waves.
(h) show an understanding that polarisation is a phenomenon associated with transverse waves.
(i) recall and use Malus’law (intensity
) to calculate the amplitude and intensity of a plane polarised electromagnetic wave after transmission through a polarising filter.
Determination of frequency and wavelength of sound waves
(j) determine the frequency of sound using a calibrated oscilloscope.
(k) determine the wavelength of sound using stationary waves.*
