(a(i))[2]
Electromagnetic waves are used in many ways. On Fig. 5.1, draw one line from each use to the region of the electromagnetic (e-m) spectrum that it belongs to.
(a(ii))[1]
State one advantage of using microwaves instead of radio waves to transmit mobile (cell) phone signals.
(b)[2]
Describe how transverse waves differ from longitudinal waves.
(c(i))[1]
State which wave type P-waves can be modelled as.
(c(ii))[2]
Explain the reason for the change in direction of the P-wave at point X.
(d)[2]
Explain what is causing the average temperature to rise.
