2 cards from this section. Quick, good the night before a test.
Define amplitude in the context of a progressive wave.
Think about how far particles move from a resting position.
What does the phase of a wave describe?
Consider how phases determine wave positioning.
What does the term 'amplitude' refer to in a wave?
Remember it describes how 'big' the wave is at its highest point.
True or False: The wavelength is the total length of a wave cycle.
Think of it as the repeatable segment of the wave.
A wave is described by y(x, t) = 0.2 sin(3x - 5t). What is the speed of this wave?
Use the relationship v = ω/k to find the speed.
If a wave has a wavelength of 1.5 m and frequency of 2 Hz, what is its speed?
Identify the terms in the wave equation to calculate speed.
