Waves, Energy and Information - Benchmark Amplify

What is sound energy?

• Sound energy is a type of energy that is produced when objects vibrate, creating waves that travel through the air or other mediums to our ears.

• Sound energy is the energy produced by chemical reactions in the atmosphere.

• Sound energy is the energy that is stored in the bonds of chemical compounds.

• Sound energy is the energy generated by the movement of electrons in a conductor.

What is a wave?

• A wave is a disturbance that transfers energy from one place to another without transferring matter.

• A wave is a solid object that moves through space.

• A wave is a type of particle that carries mass.

• A wave is a stationary phenomenon that does not involve energy transfer.

What is a trough in a wave?

• The highest point of a wave, opposite to the trough.

• The lowest point of a wave, opposite to the peak.

• The point where the wave begins to break.

• The distance between two consecutive peaks.

Why is it important for engineers to test their models?

• To ensure they meet design criteria and to identify any potential failure points.

• To reduce the cost of production.

• To increase the speed of the design process.

• To eliminate the need for documentation.

What is a frequency?

• The speed of sound in air.

• The number of waves that pass a point in one second, measured in Hertz (Hz).

• The distance between two consecutive waves.

• The amplitude of a wave.

How does sound energy travel at a concert?

• Sound energy travels in a straight line from the source to the audience.

• Sound energy moves from the source, like a piano, to the audience's ears.

• Sound energy is absorbed by the walls and does not reach the audience.

• Sound energy travels only through the air and not through any other medium.

What is the difference between sound and light waves?

• Sound waves are electromagnetic and can travel through a vacuum, while light waves are mechanical and require a medium to travel.

• Sound waves are mechanical and require a medium to travel, while light waves are electromagnetic and can travel through a vacuum.

• Sound waves travel faster than light waves in a vacuum.

• Light waves are audible, while sound waves are not.

What are the two main types of waves?

• Mechanical waves and acoustic waves

• Mechanical waves and electromagnetic waves

• Electromagnetic waves and gravitational waves

• Mechanical waves and seismic waves

What is wavelength?

• Wavelength is the distance between two consecutive peaks or troughs in a wave, which determines how close together the waves are.

• Wavelength is the speed at which a wave travels through a medium.

• Wavelength is the amplitude of a wave measured from the rest position.

• Wavelength is the frequency of a wave multiplied by its speed.
