Learning Goal: I can
- ...compare and contrast the characteristics of both a vibration and a wave.
- ...distinguish between a transverse wave and a longitudinal wave, and identify the identifying characteristics of each.
- ...distinguish between constructive and destructive interference.
- ...describe what factors may affect the speed of a wave.
- ...describe a standing wave and how it occurs.
- ...describe the Doppler Effect.
Today: Wave Pulse Superposition Practice
This is a simulation of the interference of two wave pulses on a string. Choose the shapes of the pulses either by manually moving the orange and blue points up or down or by selecting from the gallery of pre-set pulse shapes on the right.
- To practice pulse addition, uncheck the "Choose Pulse Sum" checkbox, and select the "Draw Your Own" checkbox.
- Move the pulses manually so that they partially or completely overlap.
- Now move the green points to make your prediction of the shape of the sum of the two pulses.
- When you think you have the correct shape, choose "Show Pulse Sum" to see if you were correct. Note that the green points can be moved left and right as well as up and down.
- Complete at least 4 different pulse combinations - different shapes and orientations (above-below). Sketch both of the individual pulses and the resultant pulse sum for each in your physics notebook.
- When completed, work on pp. 10-12 in the practice packet.
