1. Rags to Riches!!

2. Question 1
We have studied two types of waves. Which wave’s motion can be illustrated by a rope?
TRANSVERSE WAVE

3. Question 2
A sound wave begins with a VIBRATION

4. Question 3
What do we call “a disturbance that travels through a medium as a longitudinal wave”? VIBRATION

5. Question 4
What do we call “the material through which a wave travels”? MEDIUM

6. Question 5 Which of the following can NOT act as a medium? Gases
Empty space
Solids
liquids

7. Question 6 A reflected sound wave is called a(n): Elasticity Density
Echo
Disturbance

8. Question 7
What do we call waves which “move the medium at right angles to the direction in which the waves travel””? TRANSVERSE WAVE

9. Question 8
Give an example of “a wave that can travel without a medium”? LIGHT WAVE

10. Question 9
Sound is an example of which type of wave? LONGITUDINAL WAVE

11. Question 10
The speed of sound depends on all of the following properties of the medium EXCEPT:
Temperature
Elasticity
Density
Loudness

12. Question 11
The interaction of sound waves is called? INTERFERENCE

13. Question 12
Headphones use DESTRUCTIVE INTERFERENCE to minimize noise from outside environment.

14. Question 13
Some of a wave’s energy is always being dissipated as heat. In time, this will reduce the wave’s:
Frequency
Wavelength
Speed
Period
Amplitude

15. Question 14
When two or more waves are at the same place at the same time, the resulting effect is called:
A standing wave
A Doppler effect
A shock wave
Interference
A period

16. Question 15 What are the units for: Frequency= Hz Wavelength = m
Time Period= s
Loudness= dB
Amplitude= m

17. State whether the following are true or false:
Wavelength and frequency are directly related. F
Loudness is a measure of intensity of the sound. T
Mass has an impact on the time period of a swinging pendulum. F
The cracking of a wine glass in a Oprah singer’s show is due to Doppler’s effect. F
Amplitude of a longitudinal wave is a measure of the horizontal distance of vibrating particles from their resting position. T
Destructive interference has an additive affect. F
Echolocation can be done to locate objects by releasing infrasonic waves. F
Tacoma Narrows Bridge breakdown is an example of damping. F
Antinodes are points of maximum amplitude. T
Beats are an application of interference. T
A SHM is represented by a cosine. F
