HW-Science practice (3)Introduction to waves

Which of the following waves has the same frequency?

• A and B
• B and C
• C and D

Which of the following waves has the lowest frequency?

• X
• Y
• Z

The image below shows a model of a tsunami in which water waves of great energy can develop. Wave X has an amplitude of 2 meters. Wave Y has an amplitude of 6 meters. How does the energy of wave Y compare to the energy of wave X?

• Wave Y has more energy than X
• Wave Y has less energy than X
• Wave Y and X have the same energy

Which of the following waves has shortest wave length?

• X
• Y
• Z

Two sound waves (wave X and wave Y) are moving through a medium at the same speed. If wave X has a lower frequency than wave Y, then wave X

• has a shorter wavelength.
• has a longer wavelength.
• has a lower amplitude.
• has a greater amplitude.

A wave has a Wavelength of 5 meters and a Frequency of 10 Hz. What is the speed?

• 50 m/s
• 5 m/s
• 15 m/s
• 100 m/s
