1. Wave Properties Nat 4 Physics Nat 4 Physics

2. Starter You have 4 minutes to make a note or mind map on everything you know about waves. Try to include: -Descriptions -Diagrams -Examples

3. Learning Intention : To explore the properties of waves Why? The study of waves is fundamental to Physics. Waves are all around us, and interpreting these waves allows us to make sense of life and the universe. How? Discussions, experiments, videos & questioning. Success Criteria I can describe that waves transfer energy. I understand the meaning of the terms frequency, wavelength, trough, crest and amplitude.

4. Watch the following wave videos https://www.youtube.com/watch?v=1NJHHA9bp5Y

5. Watch the following wave videos https://www.youtube.com/watch?v=TfYCnOvNnFU

6. Waves -More than just the sea If you have ever been out on a windy day you will know the strength of a sea wave. Waves can also be extremely destructive. Waves are not just only found in water, but we will start there to learn some more about them.

7. Waves Experiment -More than just the sea Collect a glass or bowl and fill it to a depth of around 4cm. Using your finger, tap the water in the middle of glass/bowl. What do you see the water doing? Why is it doing that? Now change the rate at which you tap your finger and change the depth to which you tap. What affect does this have on the water? You are creating waves! When you tap you finger you are causing the water molecules to move up and down. These molecules cause the molecules next to them to do the same and the effect spreads. We say waves transfer energy.

8. Waves Waves transfer energy from one point to another, they do this by vibrating particles up and down or back and forth. All sorts of things in physics can be represented by waves. Fill in the following labels on your wave diagram

9. Make a copy of this diagram and add on the labels on the following slides The axis is the line running through the middle of the wave pattern.

10. The crest is the top part of the wave

11. and the trough? The trough is the bottom part of the wave.

12. What is the amplitude of the wave? The amplitude is the distance from the axis to the crest

13. or from axis to trough.

14. The wavelength is the distance after which the wave pattern repeats itself the distance between two identical points on the wave wavelength wavelength

15. Plenary What is the highest point on a wave called? What do all waves transfer? Explain how you could make different sized waves in a tray of water, using the word energy .

16. Time to Submit Your Work! Please upload a copy or photo of your work to teams, or email to Miss Dornan at tegan.dornan@castlebrae.edin.sch.uk
