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
