ANSWER:
Whisper

14. Topic 3 – 40 Points QUESTION: ANSWER:
Does amplitude affect the speed of a wave? Why?
ANSWER:
No, if you look at the equation, only wavelength and frequency will affect the speed of a wave.

75 m/s

17. Topic 4 – 30 Points QUESTION: ANSWER:
How can I increase the speed of a wave?
ANSWER:
Increase the frequency or increase the wavelength

18. Topic 4 – 40 Points QUESTION: ANSWER: Which wave is traveling faster?
A. A wave with a wavelength of 10m and a frequency of 13 Hz
B. A wave with a wavelength of 5m and a frequency of 30 Hz
ANSWER:
(B)

19. Topic 5 – 10 Points QUESTION: ANSWER:
As the frequency of a wave increases what happens to the wavelength?
What kind of relationship is this?
ANSWER:
Decreases
Negative

20. Topic 5 – 20 Points QUESTION: ANSWER:
Draw a wave on the whiteboard that has an amplitude three times the wavelength
ANSWER:

21. Topic 5 – 30 Points QUESTION: ANSWER:
I have a wavelength of 4 m and a wave speed of 16 m/s. What is the frequency of the wave?
Hint: First write out the equation you are using
ANSWER:
Wavelength x frequency = wave speed
4m x ? = 16 m/s
? = 4 Hz because 4 x 4 = 16
