Compare and contrast transverse and longitudinal waves.
understand different colours of light have different wavelengths and frequencies.
link loudness of sound to amplitude and pitch of sound to frequency.
understand that light waves can travel through a vacuum
understand that sound requires a medium to travel through - solid, liquid or gas.
carry out calculations using v = f X
describe an Earthquakes as generating S and P waves.
describe S waves as transverse and P waves as longitudinal.
A wave is a disturbance that propagates energy from one place to another without transporting any matter. A general example would be a stone hitting the surface of the water and creating ripples that travel in the shape of concentric circles with its radius increasing until they strike the boundary of the pond. There are various types of waves and two of those would be longitudinal and transverse waves.
In a longitudinal wave, the medium or the channel moves in the same direction with respect to the wave. Here, the movement of the particles is from left to right and force other particles to vibrate.
In a transverse wave the medium or the channel moves perpendicular to the direction of the wave. Here, the particles move up and down as the waves move horizontally.
