What are the similarities and differences between different types of waves? How can the wave model describe the transmission of energy as a result of local disturbances in a medium? What effect does a change in the frequency of oscillation or medium through which the wave is travelling have on the wavelength of a travelling wave?
How can light be modelled as an electromagnetic wave?
What happens when waves overlap or coincide?
How can the length of a wave be determined using concepts from kinematics?
Why does the intensity of an electromagnetic wave decrease with distance according to the inverse square law?
