Science 7 Q3 Review 4

If you will measure a wave from the crest to the next crest, what are you measuring?

• amplitude

• wavelength

• frequency

• period

Which of the following is the unit for frequency in waves?

• Meters

• Meters per Second

• Hertz

• Seconds

"A transverse wave traveling on a rope has a wavelength of 0.07 m. If the frequency of the wave is 5 Hz, what is its speed?" In the word problem, which given information below are properly labeled?

• wavelength = 0.07 m, speed = 5 Hz

• speed = 0.07 m, frequency = 5 Hz

• wavelength = 0.07 m, frequency = 5 Hz

• wavelength = 5 Hz, frequency = 0.07 m

"A transverse wave traveling on a rope has a wavelength of 0.07 m. If the frequency of the wave is 5 Hz, what is its speed?"

Given the formula:wave speed = wavelength x frequency,

which of the following will be the correct answer?

• 0.035 m/s

• 0.35 m/s

• 3.5 m/s

• 35 m/s

Study the picture.

What is the amplitude of this wave?

• 1 meter

• 2 meters

• 3 meters

• 4 meters

Study the picture. What is the wavelength of this wave?

• 1 meter

• 2 meters

• 3 meters

• 4 meters

Study the picture. Given the formula:

wave speed = wavelength x frequency.

What will be the wave speed if the frequency is 5Hz?

• 5 m/s

• 10 m/s

• 2.5 m/s

• 3 m/s

Study the image. Which points show the crests of this wave?

• A, C, E, and G

• B, D, and F

• B and F

• A and C

Study the image. Which point show the trough of this wave?

• A

• B

• C

• D

Study the image. You want to measure the wavelength. Which points should you measure?

• A to C

• B to F

• C to E

• D to G
