  4. Question 3 • What is the amplitude of the wave? • a. 24 m b. 2.5 m c. 1.5 m d. 5 m b.

  5. Question 4 • True or False? • To compare the energy of different waves, measure the wavelength of the waves. False, Energy is related to frequency.

  6. Question 5 • Transverse and longitudinal waves both • a. have compressions and rarefactions. • b. transfer energy through a medium. • c. are capable of moving the medium a long distance. • d. move at right angles to the vibration of the medium. b.

  7. Question 6 • Which letter represents the amplitude? • a. A b. B c. C d. D e. E e.

  8. Question 7 • In longitudinal waves the motion of the vibration is ____ to the direction in which the wave travels. • a. transverse • b. parallel • c. perpendicular • d. in a circular motion b.

  9. Question 8 • You are shaking the end of a rope to make a wave. You start shaking the rope the same distance, but more rapidly. What happens to the frequency and wavelength? • a. both frequency and wavelength decrease • b. both frequency and wavelength increase • c. frequency increases; wavelength decreases • d. frequency decreases; wavelength increases c.

  10. Question 9 • What is the difference between wave A and wave B? • a. Wave B has an amplitude that is one half the amplitude of wave A. • b. Wave B has a wavelength that is 4 times that of wave A • c. Wave A has a wavelength that is 3 times that of wave B • d. Wave A has an amplitude that is one half the amplitude of wave B A.

  11. Question 10 • What is the difference between wave C and wave D? • a. Wave C has a frequency half that of wave D; Therefore, the wavelength in wave D is one half that of wave C. • b. Wave D has a frequency twice that of wave C; Therefore, the wavelength in wave D is twice that of wave C. • c.
