a
b
c
d

multiple choice 2 points
the rate at which a wave travels from one point to another determines the waves
frequency
period
amplitude
velocity

Explanation:

Step1: Recall the definition of amplitude

Amplitude is the maximum displacement from the rest position of a wave.

Step2: Analyze the waves in the diagram

By visually comparing the maximum displacements of waves A, B, C, and D from the rest position (the mid - line of the wave graph), wave A has the largest maximum displacement.

Step1: Recall the definitions of wave properties

• Frequency: The number of complete waves passing a point per second ($f=\frac{n}{t}$).
• Period: The time taken for one complete wave to pass a point ($T=\frac{t}{n}$).
• Amplitude: The maximum displacement from the rest position.
• Velocity: The rate at which a wave travels from one point to another ($v = \frac{d}{t}$, where $d$ is the distance traveled by the wave and $t$ is the time taken).
