1.Change the Wave Amplitude from a high value to a low value. In terms of particle motion, how would you describe the difference between a high amplitude wave and a low amplitude wave?

ans:

2.The wavelength of a wave refers to the length of the repeating pattern of crests and troughs. Long wavelength waves have crests that are spaced relatively far apart. Short wavelength waves have crests that are relatively close to each other. Use the controls to determine two ways to increase the wavelength of the waves. Describe what you did to increase the wavelength.

ans:

3.Set the animation to Show Waves as Sound using a Real Time tempo and Frequency, Wave Speed, and Wave Amplitude values of 0.10 Hz (approximately), 100 cm/s, and 2 cm respectively.

Observe the motion of the three colored air particles. Describe the motion of these particles for a sound wave moving through air.

ans:

4.Use the Frequency slider to observe the effect of frequency upon the motion of particles in the medium. How does the particle motion differ for a high frequency wave compared to a low frequency wave?

ans:
Sound waves traveling through air are a type of wave known as a longitudinal wave. For longitudinal waves, compare the direction that the particles move to the direction that the wave moves?
