QUESTION:
•What do waves transfer?
ANSWER:
•Energy
QUESTION:
•Give an example of waves in every day life and why they are important
ANSWER:
•May Vary
QUESTION:
•Draw a wave that is getting louder
ANSWER:
QUESTION:
•Draw a wave that has a decreasing pitch
ANSWER:
QUESTION:
•What is frequency?
ANSWER:
•The number of waves per second
QUESTION:
•What unit do we measure frequency in?
ANSWER:
•Meters/second or Hz
QUESTION:
•How could I decrease the pitch of a guitar string?
ANSWER:
•By removing your finger from the fret to increase the wavelength
QUESTION:
•Demonstrate via your voice changes in frequency without changes in amplitude
ANSWER:
QUESTION:
•Draw a wave with a frequency of 4 on the white board
ANSWER:
QUESTION:
•With you group members using your arms demonstrate a wave with low frequency first and then a wave with high frequency
ANSWER:
•(type answer here)
QUESTION:
•Demonstrate a conversation with your group members demonstrating low amplitude
ANSWER:
•Whisper
QUESTION:
•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.
QUESTION:
•What unit do we measure wave speed in?
ANSWER:
•Meters/second
QUESTION:
•I have a wavelength of 15m and a frequency of 5 Hz. What is the speed of the wave?
ANSWER:
•75 m/s
QUESTION:
•How can I increase the speed of a wave?
ANSWER:
•Increase the frequency or increase the wavelength
QUESTION:
•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)
QUESTION:
•As the frequency of a wave increases what happens to the wavelength? •What kind of relationship is this?
ANSWER:•Decreases•Negative
QUESTION:
•Draw a wave on the whiteboard that has an amplitude three times the wavelength
ANSWER:
QUESTION:
•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
