Introduce waves as disturbances that transfer energy, Introduce software used in the unit to revise the link between pitch and frequency, Demonstrate transverse and longitudinal waves

1. The wave model of radiation 21st Century Physics

2. 10 October 2010 6.1 What is a wave? How many types of wave have you heard of in everyday use? Do they have anything in common?

3. Aims Introduce waves as disturbances that transfer energy Introduce software used in the unit to revise the link between pitch and frequency Demonstrate transverse and longitudinal waves

4. Introduction to waves

5. What is a wave? A wave is a disturbance moving through a material

6. What causes a wave? The source of a wave is always something thatvibrates The material that the wave travels through is called the medium

9. Low frequency, high period High frequency, low period

10. Transverse T

11. Transverse The particles of the medium vibrate at right angles (perpendicular) to the direction in which the wave moves

12. aLong Longitudinal

13. Longitudinal The particles vibrate (oscillate) back and forth creating a continuing wave of pulses

18. Water waves
