Wave Properties

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 exclusively by submarines.

• A way for birds to navigate using the stars.

What do waves transfer from place to place?

• Matter from one location to another.

• Energy from one location to another.

• Information from one location to another.

• Sound from one location to another.

What is the height of a wave called?

• Frequency

• Wavelength

• Amplitude

• Crest

What do sound waves require to travel?

• A vacuum

• Particles

• Electric fields

• Magnetic fields

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 fluctuates randomly.

What is wavelength?

• The time it takes for a wave to complete one cycle.

• 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.

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.

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 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 fixed position in space that does not change.

• A wave is a form of matter that cannot be seen.

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 only affected by humidity, not temperature.
