Sound Review

Question 0

2. What is needed to create a sound wave?

Answer 0

A source of energy to create a vibration

Question 1

1. What kind of waves are sound waves?

Answer 1

Sound waves travel through mediums as Longitudinal waves

Question 2

3. Describe two parts of a sound wave.

Answer 2

Compression and refraction.

Question 3

4. Know what a sound wave can and cannot travel through

Answer 3

CAN: A medium (gas, liquid, solid)

CANNOT: In outer space

Question 4

5. Where does a sound wave have the most energy and produce the loudest sound?

Answer 4

Near the source with a higher amplitude

Question 5

6. How does density affect the speed of sound

Answer 5

Density affects sound because the denser the materiel it is harder for the materials to move as a sound wave passes by.
Denser- slow
Less Dense- FAST

Question 6

7. What are the three factors that affect sound?

Answer 6

Temperature
Density
Stiffness

Question 7

8. How does temperature affect the speed of sound

Answer 7

Temperature affects the speed of sound because when it is hotter sound moves fast and when it is cold sound moves slower

Question 8

9. How does stiffness affect the speed of sound

Answer 8

Stiffness affects the speed of sound because if the medium is stiff it goes faster and vise versa
