Topic 4 general notes
This is tied to Topic 9. I have taught them as 2 intertwined units (4.1, 9.1, 4.2, 4.3, 4.4, 9.2, 9.3, 9.4, 4.5, 9.5) as well as teaching all of Topic 4 first. Both can be made to work. A good understanding of Topic 4 is vital to success in Topic 9.
Again, lots of opportunities for experiments here.

Practical Ideas:
|
- Using a slinky to demonstrate longitudinal and transverse waves
- Using a prism to separate white light - Using blue red and green LEDs to combine and make white light - Bell in a vacuum jar to demonstrate the need for a medium |

Veritasium - Light and Interference

Wave Characteristics Playlist (See videos 1 and 7)
|
|
Practical Ideas:
|
- I cut up polarizing sheets into 4cm x 4cm squares and have students look at different things through them like sunglasses while rotating them. You can look at the glare off of cars in the parking lot. They like just looking at each other. Also polarizers in front of your projector light can work nicely.

Wave Behaviour Playlist (See videos 2-4 and 6)
|
|
Practical Ideas:
|
- Snell's Law experiment to determine refractive index
- Using a water table to demonstrate wave behaviour near barriers (PhET has a pretty good simulation as well - Setting up 2 speakers playing a coherent tone and having students use their ear or sound sensors to find nodes and anti-nodes in a room (room needs to have poor acoustic reflection) |

Making a Ruben's Tube (Demo at the end is very cool)

Veritasium - Pyro Board (2D Ruben's Tube)
|
|
|
Practical Ideas:
|
- Creating standing waves with a slinky to demonstrate nodes, anti-nodes and the effect of changing frequency
- Using a simulation to do the same as above but more specifically (See PhET) - Creating standing waves over a burette |
