3 Waves – Part B “Properties of Waves”

Syllabus Aims…

3.3 know the definitions of amplitude, wavefront, frequency, wavelength and period of a wave

3.4 know that waves transfer energy and information without transferring matter

3.5 know and use the relationship between the speed, frequency and wavelength of a wave:

wave speed = frequency × wavelength

v = f × λ

3.6 use the relationship between frequency and time period: frequency = 1/time period

f = 1/T

3.7 use the above relationships in different contexts including sound waves and electromagnetic waves

3.2 explain the difference between longitudinal and transverse waves

3.9 explain that all waves can be reflected and refracted.

3.8 explain why there is a change in the observed frequency and wavelength of a wave when its source is moving relative to an observer, and that this is known as the Doppler effect  (May be covered in Y10)

Resources…

• Use this PowerPoint for a quick review…3 Waves Part B Properties
• Doppler Effect

Video Resources…

Wave Properties: This video explains the basic idea of a “waveform” and ripple tank to show “displacement” or amplitude over a period of time “T” with equations…

Period / Frequency: This video shows you how to do calculations for waves…

Longitudinal & Transverse: A super clear explanation of all the basic labels for wave and T and T waves.

String Waves: This is the required GCSE practical for AQA which is a way to work out the Speed of a wave on a string.

Doppler Shift: Example how how it sounds!

Doppler Shift: This shows now it works with compression or expansion of wave forms or a shift in wavelength

104 - Wave Period and Frequency

In this video Paul Andersen explains how the period is the time between wave and the frequency is the number of waves per second. Period is measured in seconds and frequency is measured in Hertz. Wave period and wave frequency are reciprocals of one another. After watching this video you will be able to determine the period (and therefore the frequency) using a position vs. time graph of a wave.

This is a typical quick classical Physics demo of a slinky to show longitudinal and transverse waves. I have put a scale of 0.5m on the wavelength so you can work out a whole wavelength. Also you have a small amplitude scale to show the energy of the wave.Show More
