Wave Properties

What happens to the amplitude of a wave when more energy is added?

• The amplitude of a wave decreases.

• The amplitude of a wave remains the same.

• The amplitude of a wave increases when more energy is added.

• The amplitude of a wave becomes unpredictable.

What do sound waves require to travel?

• A vacuum

• Particles

• Electric fields

• Magnetic fields

What do waves transfer from place to place?

• Information

• Matter

• Energy

• Sound

What is echolocation?

• A method used by animals to communicate and locate objects using sound waves.

• A technique for visualizing underwater landscapes.

• A form of sonar used in submarines.

• A way for birds to navigate during migration.

What is the difference between mechanical waves and electromagnetic waves?

• Mechanical waves can travel through a vacuum, while electromagnetic waves cannot.

• Mechanical waves require a medium to travel through, while electromagnetic waves do not.

• Mechanical waves are faster than electromagnetic waves.

• Mechanical waves are a type of electromagnetic wave.

What is a rarefaction in a sound wave?

• A region in a sound wave where particles are spread apart.

• A region in a sound wave where particles are compressed together.

• A type of sound wave that travels faster than light.

• A phenomenon that occurs only in liquids.

What is frequency in relation to waves?

• Frequency is the number of waves that pass a point in one second.

• Frequency is the speed at which waves travel through a medium.

• Frequency is the distance between two consecutive waves.

• Frequency is the amplitude of the waves.

What is wavelength?

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

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

• The amplitude of a wave measured from its rest position.

• The frequency of a wave measured in hertz.

What is a wave?

• A wave is a disturbance that transfers energy through space or matter.

• A wave is a solid object that reflects light.

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

• A wave is a stationary object that does not move.

What is a compression in a sound wave?

• A region in a sound wave where particles are close together.

• A region in a sound wave where particles are far apart.

• A type of sound wave that is low in frequency.

• A sound wave that has been amplified.
