Chapter 15 Waves Section 2

Waves have measurable properties.

Open Ended

Make a simple diagram of a wave, labeling amplitude, frequency, and wavelength. For frequency, you will need to indicate a span of time, such as one second. Answer this one on a sheet of paper.

Multiple Choice

What two measurements of a wave do you need to calculate speed?

• wavelength and frequency

• acceleration and force

• speed and frequency

• wavelength and force

Multiple Choice

Suppose you are watching water waves pass under the end of a pier. How can you figure out their frequency?

• Pick a point of reference and time how many waves pass that point within a given amount of time.

• Count how many crests and troughs you see within a given amount of time.

Multiple Choice

A wave has a speed of 3 m/s and a frequency of 6 (waves)/s. What is the wavelength.

• 3 x 6 = 18

• 6/3 = 2

• 3/6 = 0.5
