Physical Science - Waves Review

What is wave speed?

• The speed at which sound travels through air.

• The distance a wave travels per unit of time, calculated as wavelength times frequency.

• The rate at which light travels in a vacuum.

• The speed of a wave in a medium, independent of its frequency.

What is a wavelength?

• The distance between two consecutive crests or troughs in a wave.

• The speed at which a wave travels through a medium.

• The amplitude of a wave measured from the equilibrium position.

• The frequency of a wave measured in hertz.

What is rarefaction in a wave?

• Rarefaction is the region in a longitudinal wave where the particles are spread apart.

• Rarefaction is the point in a wave where the particles are closest together.

• Rarefaction refers to the amplitude of a wave.

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

What is the amplitude of a wave?

• The amplitude is the maximum distance that the particles of a medium move from their rest position when a wave passes through.

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

• The amplitude is the frequency of the wave measured in hertz.

• The amplitude is the wavelength of the wave, which is the distance between two consecutive peaks.

What is the principle of superposition in wave theory?

• The principle of superposition states that when two or more waves overlap, the resulting wave displacement is the sum of the individual displacements.

• The principle of superposition states that waves can only exist independently without interaction.

• The principle of superposition states that the speed of a wave is constant regardless of the medium.

• The principle of superposition states that waves can only interfere destructively.

What is a trough in a wave?

• The highest point of a wave.

• The lowest point of a wave.

• The distance between two consecutive crests.

• The speed at which a wave travels.

What is a crest in a wave?

• The lowest point of a wave.

• The highest point of a wave.

• The distance between two crests.

• The speed at which a wave travels.

What is a medium in the context of waves?

• A medium is a type of wave that travels through space.

• A medium is the substance through which a wave travels, such as air, water, or solid materials.

• A medium is a measurement of the frequency of a wave.

• A medium is the speed at which a wave travels.

What is frequency in relation to waves?

• The speed at which waves travel through a medium.

• The distance between two consecutive waves.

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

• The amplitude of the waves measured in decibels.

How do mechanical waves propagate energy?

• Mechanical waves propagate energy as particles of a medium vibrate.

• Mechanical waves propagate energy through the vacuum of space.

• Mechanical waves propagate energy by creating electromagnetic fields.

• Mechanical waves propagate energy by transferring heat through conduction.
