Question:
An oscillator creates periodic waves on a stretched string.
a) If the period of the oscillator doubles, what happens to the wavelength and wave speed?
1) The wavelength doubles but the moving ridge speed remain unchanged.
2) The wavelength is halved only the moving ridge speed is unchanged.
three) The wavelength is unchanged but the wave speed doubles.
b) If the aamplitude of the oscillator doubles, what happens to the wavelength and wave speed?
1) Both wavelength and wave speed are unchanged.
2) The wavelength is unchanged but the wave speed doubles.
3) The wavelength doubles but the wave speed remain unchanged.
Characteristics of Wave:
A transverse moving ridge is formed in the string, by creating oscillations from one end of the string, which travel along the length of the string, with its feature speed, frequency wavelength and aamplitude of the moving ridge.

fifteen. The number of cycles of a periodic wave occurring per unit of measurement time is defined as a wave's ____.
a. wavelength.
b. period.
c. amplitude.
d. frequency.
Reply: D
This is a basic definition which yous should know and be able to utilize.
16. A periodic and repeating disturbance in a lake creates waves which emanate outward from its source to produce circular wave patterns. If the frequency of the source is ii.00 Hz and the wave speed is 5.00m/southward so the distance between adjacent wave crests is ___ meter.
a. 0.200
b. 0.400
c. 1.25
d. 2.l
e. 10.0
Answer: D
Let w=wavelength; then v = w*f. In this problem, information technology is given that v=5.00 thou/southward and f = ii.00 Hz. Substitution and algebra yields w = v / f = 2.50 m.

17. What is the frequency of a wave that has a speed of 0.iv m/s and a wavelength of 0.020 meter?
a. 10 hertz.
b. twenty hertz.
c. 0.008 hertz.
d. 0.five hertz.
Reply: B
Permit w=wavelength; and so 5 = w*f. In this problem, information technology is given that v=5 m/south and westward = .02 m. Commutation and algebra yields f=v/w=20 Hz.

18. Many wave properties are dependent upon other wave properties. Withal, one wave property is independent of all other wave properties. Which 1 of the following properties of a wave is independent of all the others?
a. wavelength
b. frequency
c. period
d. velocity
Answer: D
The speed of a wave is dependent upon the properties of the medium through which it moves, not upon the properties of the wave itself.

19. A pendulum makes exactly 40 vibrations in xx.0 southward. Its menstruation is ____. (Be cautious of the units.)
a. 0.500 Hz.
b. 0.500 due south.
c. 2.00 Hz.
d. ii.00 s.
e. 8.00 ten 102 Hz.
Respond: B
The period is the time for ane consummate cycle. If the pendulum takes 20.0 seconds for exactly forty vibrational cycles, and so it must take 0.500 2d for one bike.

20. A menstruation of 0.005 seconds would exist equivalent to a frequency of ____ Hz.
a. 20
b. 50
c. 200
d. 500
e. 2000
Answer: C
The period and the frequency are related by a reciprocal human relationship; that is, f = i/T.

a. Truthful
b. Fake
Reply: B
Don't be fooled. Wave speed may equal frequency*wavelength. Yet doubling the frequency only halves the wavelength; wave speed remains the same. To alter the wave speed, the medium would have to be changed.
24. If the frequency of a wave is doubled and if the speed remains constant, its wavelength is ____.
a. quartered.
b. halved.
c. unchanged.
d. doubled.
Answer: B
Wave speed equals frequency*wavelength. And so doubling the frequency must halve the wavelength in social club for wave speed to remain the aforementioned.

25. Ii different ropes with different mass densities are attached to each other. A pulse is introduced into one end of the rop and approaches the boundary as shown at the right. At the purlieus, a portion of the energy is transmitted into the new medium and a portion is reflected. Which 1 of the diagrams below depicts the possible location and orientation of the pulse shortly after the incident pulse reaches the purlieus?
Respond: C
The speeds in the two media can be deduced by the distance of the pulses from the boundary. In A and Eastward, the speed is shown as fastest on the right, which makes the transmitted medium the less dumbo. Dominion out A and E since a reflected pulse should not invert when moving from more dumbo to less dens. Dominion out B for just the opposite reasons; the wave is moving from less to more dense and should invert upon reflection. Rule out D considering the transmitted pulse never inverts. That leaves C as the respond.

26. When a pulse reaches a boundary between two different media, it volition be____.
a. reflected, just.
b. transmitted, only.
c. partly reflected and partly transmitted.
d. neither reflected nor transmitted.
Answer: C
This is basic information nigh the boundary behavior of waves.
