Unit 14. Waves - Part 1


A Level


12m 11s
This topic introduces the basic properties of transverse and longitudinal progressive waves, including the determination of the frequency and speed of sound waves. The electromagnetic spectrum is also introduced. These basic properties of waves are developed further into a study of the Doppler effect and of ultrasound for diagnostic purposes. The ideas of simple wave behaviour, such as reflection and refraction of light, would be useful prior knowledge. This tutorial discusses: Progressive waves, Transverse and longitudinal waves, Determination of frequency and wavelength of sound waves, Doppler effect, Electromagnetic spectrum, Production and use of ultrasound in diagnosis
