- Bwavelength
3When we consider the time it takes for a pendulum to swing to and fro, we're talking about
- AFrequency
- BPeriod
4If the frequency of a particular wave is 20 Hz, it's period is
- A20 seconds
- B1/20 second
5When we consider how far a pendulum swings to and fro, we're talking about its
- Aamplitude
- Bperiod
6What is carried from one location to a distant location by a wave is
- Aenergy
- Bwavelength
7The speed of a wave can be found by multiplying its frequency by its
- Adensity
- Bwavelength
8As a water wave of wavelength 4 m passes by a portion of water vibrates up and down two complete cycle in 1 second. The speed of the wave is
- A2 m/s
- B8 m/s
9Sound waves are
- ALongitudinal
- BTransverse
10The vibration along a transverse wave move in a direction
- Aalong the wave
- Bperpendicular to the wave
11The vibrations along a longitudinal wave move in a direction
- AAlong and parallel to the wave
- Bperpendicular to the wave
12A common example of a transverse wave is
- Asound
- Blight
13To produce a longitudinal wave in a coiled spring, shake the coil
- Aup and down perpendicular to the coil
- Bto and fro parallel to the coil
14The pitch of a sound is most closely related to its
- Afrequency
- Bamplitude

- Aputty
- Bsteel
18Sound does not travel in a
- Avacuum
- Bsolid
19The speed of sound varies with
- Aampitude
- Btemperature
20An echo typically occures when a sound wave is
- Areflected from a smooth and solid surface
- Brefracted from a polished surface
21Sound and light
- Aobey the same laws of reflection
- Bobey different laws of reflection
22On a cold night, air near the ground may be cooler than air higher above. this most likely produces
- Aan echo
- Bsound refraction
23The refraction of sound depends on differences in sound
- Afrequency
- Bspeed
24The factory floor vibrates and as a result you vibrate when standin on the floor. This is
- Aforced vibration
- Bresonance
25When the surface of a bass fiddle is made to vibrate, we say that it undergoes
- Aresonance
- Bforced vibration
26When you drop an object only a hard floor, the object will vibrate and

- Bproduce its own special sound
27When an object is set vibrating by a wave having a frequency that matches the natural frequency of the object what occurs is
- Aresonance
- Bforced vibration

31Standing waves are produced by
- Afrequency changes
- Binterference
32Sound waves can impinge on our ear in such a way as to produce
- Asilence
- Bbowed waves
33The phenomenon of beats is the result of sound
- Adestruction
- Binterference
