a) If the period of the oscillator doubles, what happens to the wavelength and wave speed?
ane) The wavelength doubles but the wave speed remain unchanged.
2) The wavelength is halved but the wave speed is unchanged.
iii) 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 moving ridge speed are unchanged.
ii) The wavelength is unchanged just the wave speed doubles.
three) The wavelength doubles but the moving ridge speed remain unchanged.
Characteristics of Wave:
A transverse wave is formed in the string, by creating oscillations from 1 end of the string, which travel along the length of the string, with its characteristic speed, frequency wavelength and amplitude of the wave.

15. The number of cycles of a periodic moving ridge occurring per unit fourth dimension is defined as a wave's ____.
a. wavelength.
b. period.
c. amplitude.
d. frequency.
Answer: D
This is a basic definition which you should know and be able to apply.
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 2.00 Hz and the wave speed is five.00m/s and then the distance between next wave crests is ___ meter.
a. 0.200
b. 0.400
c. ane.25
d. two.50
due east. ten.0
Answer: D
Permit w=wavelength; then 5 = w*f. In this problem, it is given that v=5.00 1000/s and f = 2.00 Hz. Exchange and algebra yields w = v / f = 2.50 g.

17. What is the frequency of a wave that has a speed of 0.4 g/s and a wavelength of 0.020 meter?
a. 10 hertz.
b. xx hertz.
c. 0.008 hertz.
d. 0.five hertz.
Reply: B
Let w=wavelength; and then five = west*f. In this trouble, it is given that five=5 thou/s and w = .02 grand. Substitution and algebra yields f=v/w=20 Hz.

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

19. A pendulum makes exactly twoscore vibrations in 20.0 southward. Its period is ____. (Be cautious of the units.)
a. 0.500 Hz.
b. 0.500 s.
c. two.00 Hz.
d. 2.00 s.
e. eight.00 10 10two Hz.
Reply: B
The menstruation is the time for ane consummate cycle. If the pendulum takes 20.0 seconds for exactly twoscore vibrational cycles, so it must accept 0.500 2nd for one wheel.

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

22. TRUE or FALSE:
a. True
b. False
Answer: A

[ #15 | #xvi | #17 | #18 | #19 | #twenty | #21 | #22 | #23 | #24 | #25 | #26 ]
a. Truthful
b. False
Respond: B
Don't exist fooled. Wave speed may equal frequency*wavelength. Yet doubling the frequency only halves the wavelength; wave speed remains the same. To change the moving ridge speed, the medium would have to exist 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. So doubling the frequency must halve the wavelength in society for wave speed to remain the same.

25. Ii dissimilar ropes with different mass densities are attached to each other. A pulse is introduced into ane end of the rop and approaches the boundary equally shown at the right. At the purlieus, a portion of the energy is transmitted into the new medium and a portion is reflected. Which one of the diagrams below depicts the possible location and orientation of the pulse shortly later on the incident pulse reaches the purlieus?
Answer: C
The speeds in the 2 media can be deduced by the altitude of the pulses from the boundary. In A and E, the speed is shown every bit fastest on the correct, which makes the transmitted medium the less dense. Rule 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 contrary reasons; the wave is moving from less to more dense and should capsize upon reflection. Dominion out D considering the transmitted pulse never inverts. That leaves C as the reply.

26. When a pulse reaches a boundary between 2 different media, information technology will be____.
a. reflected, only.
b. transmitted, simply.
c. partly reflected and partly transmitted.
d. neither reflected nor transmitted.
Respond: C
This is basic information nigh the boundary behavior of waves.
