Longitudinal waves means that the disturbance of the wave travels in different directions as the wave.
True
False
A back-and-forth motion causing particles to move close together generates a _________.
rarefaction
surface wave
transverse wave
compression
In which of these types of media will sound travel fastest?
solid
liquid
gas
vacuum
Which temperature causes sound to travel more slowly?
hot
cold
Frequency of waves is measured in __________.
hertz
decibels
watts
meters/second
A change in frequency results in a change of wave length; a change in amplitude does not.
true
false
What is the approximate speed of sound in air?
330 m/s
1500 m/s
5000 m/s
Sound waves can travel through all three states of matter. Which of the following best explains why sound travels most quickly through a solid?
Solids always produce an echo, which makes the sound seem louder to the human ear.
Only solids allow the vibrations to travel from one atom (particle) to another.
In solids, the atoms (particles) are closest together, which allows the vibrations to travel rapidly from one to another through the object.
Sound does not travel quickly through a solid. It travels most rapidly through a gas.
Which of the following gives the correct order of speed of sound from slowest to fastest in the given material?
air, steel, water
steel, water, air
water, air, steel
air, water, steel
Which of the following statements are TRUE on solid materials?
I. Solid materials make sound moves fast.
II. Solid materials have compact molecules.
III. Solid materials are the best materials that allows sound to moves fastest
IV. Solid materials does not allow sound particles to move faster than in other materials

Statement II: Sound may pass through different materials with different speeds.
Both statements I and II are TRUE
Both statements I and II are FALSE.
Statement I is False while statement II is TRUE.
Statement I is TRUE while statement II is FALSE.
Which of the following statements are TRUE about the speed of sound?
I. The speed of sound may vary in each material.
II. The speed of sound depends in one material.
III. The speed of sound changes as it passes through different media.
IV. The speed of sound is constant as it passes through different media.

Each object can produce a unique sound. Are all objects able to produce sound without producing any vibrations?
No, because all objects are vibrating objects.
Yes, objects can make sound without vibration.
No, because to produce sound it requires vibrations.
Yes, objects can produce sound with and without vibrations.
Loud sound means....
the frequency is higher
the amplitude is higher
the amplitude is lower
the frequency is lower
When the temperature is high in a solid object what happens to the vibration of the sound waves
vibrates fast
vibrates slow
no vibration
temperature does not affect the movement of the sound waves

Which is a part of the inner ear?
Ear canal
Eardrum
Ossicle
Cochlea
The cochlea sends signals through the ?????? in order for you brain to interpret sound?
Olfactory nerve
Visual cortex
Gustatory cortex
Auditory nerve
