Wave Properties

What is the speed of sound in air?

• 300 meters per second

• 343 meters per second

• 400 meters per second

• 250 meters per second

What is a trough in a wave?

• The highest point of a wave.

• The lowest point of a wave.

• The point where the wave starts to break.

• The distance between two consecutive waves.

How does temperature affect the speed of sound?

• The speed of sound decreases with higher temperatures because particles move slower.

• The speed of sound remains constant regardless of temperature changes.

• The speed of sound increases with higher temperatures because particles move faster.

• The speed of sound is not affected by temperature.

What is a wave?

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

• A wave is a type of particle that moves through a medium.

• A wave is a solid object that vibrates in place.

• A wave is a form of light that does not require a medium.

What is echolocation?

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

• A technique for measuring distances using light waves.

• A form of communication that involves visual signals and gestures.

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.
