# Physics: Sound and Waves

by Texas Instruments - Simulation Lesson

#### Objectives

• Students will construct an understanding of frequency, amplitude, and phase shift.
• Students will develop the understanding of the sine function and how it relates to sound waves.
• Students will simulate the addition of two waves and observe that this addition forms sound dampening and beats.

• amplitude
• beats
• dampening
• frequency
• compression
• notes
• phase shift
• sound
• waves

#### About the Lesson

In this lesson students change characteristics of a sine wave to discover the frequency, amplitude, and phase shift. They will also use these properties to see the effect of adding two waves to form dampening and beats.
As a result students will be able to:

• Define, describe, and use the different characteristics of waves (frequency, amplitude, phase shift)
• Recognize and explain the result of adding two waves together.
• Explain the effect phase shift has on the sum wave.
• Recognize and explain the effect frequency and phase shift have on the sum wave.
