On a separate sheet of paper, answer the following questions.

1. A stretched spring attached to two fixed points is compressed on one end and released as shown below. The resulting wave travels back and forth between the two fixed ends of the spring until it comes to a stop. This mechanical wave is an example of what type of wave?

This is an example of a longitudinal wave, also known as a compressional wave.

2. One end of a horizontal string is caused to oscillate vertically while the other end is attached to a fixed object. The wave that travels along the string is an example of what kind of wave?

This is an example of a standing wave. A transverse wave would also be a correct answer.

3. A sound wave traveling through a solid material has a frequency of 500 Hz. The wavelength of the sound wave is 2 meters. What is the speed of sound in the material?

4. A tuning fork is used to produce sound waves with a frequency of 440 Hz. The waves travel through the air at 344 m/s. What is the wavelength of the sound waves?

5. A student shakes the end of a rope with a frequency of 1.5 Hz, causing waves with a wavelength of 0.8 m to travel along the rope. What is the velocity of the waves?

6. What is the wavelength of a 264 Hz sound wave when the speed of sound is 345 m/s?

7. Would an astronaut on the moon be able to hear a landslide? Why or why not?

No. Sound needs a medium to travel through such as air. There is no air on the Moon.
