Question 0

2. What is needed to create a sound wave?

Answer 0

A vibration is needed to create a sound wave from an energy source.

Question 1

1. What kind of waves do sound waves travel as?

Answer 1

Sound waves travel as longitudinal waves.

Question 2

3. Describe the 2 parts of the sound wave.

Answer 2

Compression: When the medium’s particles are close together.

Question 3

4. What mediums can sound waves not travel through?

Answer 3

Sound waves cannot travel through a vacuum, and they can travel through liquids, solids, and gases.

Question 4

5. Where does the wave have the largest sound?

Answer 4

It is the loudest nearest to the energy source.

Question 5

6. How does density affect the speed of sound?

Answer 5

Dense objects make sound waves slower, because it is harder for waves to pass through it.

Question 6

7. What are the 3 factors that affect the speed of sound?

Answer 6

Temperature, Density, and Stiffness affects the speed of sound.

Question 7

8. How does temperature affect the speed of sound?

Answer 7

At higher temperatures the wave is faster, and at lower temperatures the wave is slower.

Question 8

9. How does stiffness affect the speed of sound?

Answer 8

Stiff mediums make the waves move faster.
