Order to travel, sound waves must have
-
Solid
-
Liquid
-
Gas
-
Matter
Correct Answer
A. MatterExplanation
Sound waves are mechanical waves that require a medium to travel through. This medium can be a solid, liquid, or gas, collectively known as matter. Sound waves cannot travel through a vacuum because there are no particles to transmit the vibrations. Therefore, the correct answer is matter, as sound waves require a material medium to propagate.Rate this question:

Why does blowing into a trumpet make a sound?
-
The trumpet heats the air
-
The trumpet reflects the air
-
The air in the trumpet is cooled
-
The trumpet causes air to vibrate
Correct Answer
A. The trumpet causes air to vibrateExplanation
When air is blown into a trumpet, it passes through the narrow mouthpiece and into the trumpet's tubing. The shape and length of the tubing cause the air to vibrate, creating sound waves. This vibration is amplified by the trumpet's bell, producing the characteristic sound of a trumpet. Therefore, the correct answer is that the trumpet causes air to vibrate.Rate this question:

To increase the volume of a sound you must
-
Make a smaller instrument
-
Decrease the amount of force
-
Add electricity
-
Increase the amount of force used
Correct Answer
A. Increase the amount of force usedExplanation
To increase the volume of a sound, you need to increase the amount of force used. This is because the volume of a sound is directly proportional to the amplitude of the sound wave. By increasing the force applied to an instrument, you are increasing the energy transferred to the medium (air, water, etc.) and therefore increasing the amplitude of the sound wave. This results in a louder sound.Rate this question:

If Sam is playing his guitar and wants one of the strings to create a higher pitch, what should he do?
-
Keep the string the same and use two finger to play
-
Tighten the string
-
Loosen the string
-
Replace the string with a new one
Correct Answer
A. Tighten the stringExplanation
To create a higher pitch on a guitar string, Sam should tighten the string. By tightening the string, he increases the tension, which in turn increases the pitch produced when the string is played.Rate this question:

How high or how low a sound is
-
Pitch
-
Volume
-
Reflection
-
Absorption
Correct Answer
A. PitchExplanation
Pitch refers to how high or low a sound is. It is determined by the frequency of the sound waves, with higher frequencies producing higher pitched sounds and lower frequencies producing lower pitched sounds. The pitch of a sound is not related to its volume or how loud it is, which is represented by the term "volume." Reflection and absorption are not directly related to the pitch of a sound.Rate this question:

The bouncing of a sound wave off a surface is
-
Overtone
-
Reflection
-
Frequency
-
Pitch
Correct Answer
A. ReflectionExplanation
The bouncing of a sound wave off a surface is known as reflection. Reflection occurs when a sound wave encounters a surface and bounces back. This phenomenon is similar to how light waves reflect off a mirror or a shiny surface. Reflection is an important property of sound waves and is responsible for various phenomena such as echo and reverberation.Rate this question:

The disappearance of a sound wave into a surface is
-
Decibel
-
Echo
-
Reflection
-
Absorption
Correct Answer
A. AbsorptionExplanation
Absorption refers to the process in which a sound wave is absorbed by a surface, causing it to disappear. When a sound wave encounters a surface that is capable of absorbing sound, such as a soft material or an acoustic panel, the energy of the sound wave is converted into heat energy, resulting in the disappearance of the sound wave. This is different from reflection, where the sound wave bounces off the surface, echo, where the sound wave is reflected back to the source, and decibel, which is a unit used to measure the intensity of sound.Rate this question:

Which of the following lists rates the material in order from the best sound carrier to the worst sound carrier?
-
Air, water, wood
-
Wood, water, air
-
Wood, air, water
-
Water, wood, air
Correct Answer
A. Wood, water, airExplanation
Sound travels fastest in solids, then liquids, and slowest in gases. This is because the molecules in solids are closely packed together, allowing sound waves to be transmitted more efficiently. Wood is a solid, water is a liquid, and air is a gas. Therefore, the correct order from best to worst sound carrier is wood, water, air.Rate this question:

Which part of the ear collects the sounds?
-
Hammer
-
Cochlea
-
Pinna
-
Eardrum
Correct Answer
A. PinnaExplanation
The pinna is the outer part of the ear that collects sounds. It is the visible part of the ear that protrudes from the side of the head. Its shape and structure help to capture sound waves and direct them into the ear canal. Once the sound waves enter the ear canal, they travel towards the eardrum and then further into the middle and inner ear for processing and interpretation.Rate this question:
