Determine whether each statement is true or false. Then on a separate sheet of paper, write "true" if it is true. If it is false, change the underlined word or words to make the statement true. 1. A medium transfers wave matter. 2. The crest of a wave is the maximum dis- placement upward. 3. Molecules spread out in rarefaction. 4. A transverse wave is a series of compres- sions and rarefactions. 5. The distance between two consecutive crests is one amplitude. 6. Frequency is measured in hertz. 7. The incoming wave is the standing wave. 8. The bending of waves due to a change in speed is called reflection. 9. When two waves combine to subtract from each other, destructive interference occurs. 10. Constructive interference and destructive interference producing stationary nodes and antinodes is called a diffraction wave.

13. Two-point sources vibrate in phase at the same frequency. They set up an interference pattern in which a point on the second nodal line is 29.5cm from one source and 25.0 cm from the other. The speed of the waves is 7.5cm/s. a. Calculate the wavelength of the waves b. Calculate the frequency at which the sources are vibrating [2T] [2T]

Which of the following conditions guarantees that two overlapping waves will exhibit the property of interference? O a. The waves must have the same frequencies. O b. The waves must be sinusoidal. O c. The waves must be coherent. O d. The waves must be in phase. O e. The waves must have the same amplitudes.

For the wave Y = 3cos(5t -6x), what are the following? a. Amplitude: b. Wavelength: c. Frequency:

A stretched string is 2.03 m long and has a mass of 20.3 g. When the string oscillates at 440 Hz, which is the frequency of the standard A pitch, transverse waves with a wavelength of 15.5 cm travel along the string. Calculate the tension T in the string.
