Sound and Energy

What is sound?

• Sound is a form of energy produced by vibrations and travels through a medium.

• Sound is a type of light wave

• Sound is a form of solid matter

• Sound is a type of magnetic force

How is sound produced?

• By the reflection of an object

• By the vibration of an object

• By the rotation of an object

• By the expansion of an object

What is vibration?

• A slow and steady movement of an object

• A stationary position of an object

• A side to side movement of an object

• A rapid back and forth movement of an object

How does vibration create sound?

• Vibration has no effect on air particles

• Sound is created by the movement of water

• Vibration creates light instead of sound

• Vibration causes the air particles to vibrate, creating sound waves.

What is pitch?

• Speed of a moving object

• Temperature of a liquid

• Perceived frequency of sound

• Color of the sky

How is pitch related to frequency?

• Pitch is only related to volume, not frequency

• Pitch is directly related to frequency

• Pitch is inversely related to frequency

• Pitch has no relation to frequency

What is frequency?

• The loudness of a sound

• The pitch of a sound

• The distance between two sound waves

• Number of occurrences of a repeating event per unit of time

How is frequency measured?

• In inches (in)

• In hertz (Hz)

• In miles per hour (mph)

• In pounds (lb)

What is sound energy?

• A form of energy associated with the growth of plants

• A form of energy associated with the flow of water

• A form of energy associated with the movement of light

• A form of energy associated with the vibration of matter

How is sound energy transferred?

• Through the vibration of particles in a medium

• Through the emission of heat energy

• Through the transfer of electrical currents

• Through the movement of light waves
