By the end you can

Describe transverse and longitudinal waves and read amplitude, wavelength and period from wave graphs
Use v = fλ and T = 1/f with unit prefixes and standard form
Measure the speed, frequency and wavelength of waves in a ripple tank and on a string, and of sound in a metal rod (Edexcel)
Explain reflection and refraction, and why a change of speed bends a wave
Order the electromagnetic spectrum and match each part to its uses and its dangers
Carry out and analyse the infrared radiation practical
