Wave Properties and Graph Analysis

Mrs. Winstead explains how to read wave graphs, focusing on position vs. time graphs. She describes how to identify the end of a wave cycle, calculate the period and frequency, and determine the amplitude. The video includes examples to illustrate these concepts, emphasizing the importance of understanding the equilibrium line and the repetition of wave patterns. The tutorial concludes with a summary of the techniques for analyzing wave graphs.

What is typically represented on the x-axis of a wave graph?

• Frequency

• Amplitude

• Time

• Position

How do you determine the end of one cycle on a wave graph?

• When the graph reaches its highest point

• When the graph returns to its starting position

• When the graph crosses the x-axis

• When the graph reaches its lowest point

If the period of a wave is 3 seconds, what is its frequency?

• 0.33 Hz

• 3 Hz

• 1 Hz

• 0.5 Hz

How is amplitude determined from a wave graph?

• By measuring the distance from the crest to the trough

• By measuring the distance from the x-axis to the crest

• By measuring the distance from the equilibrium line to the crest

• By measuring the distance from the equilibrium line to the trough
