Waves

What is amplitude?

• Amplitude is the maximum distance that a point on a wave moves from its rest position.

• Amplitude refers to the frequency of a wave.

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

• Amplitude is the total energy carried by a wave.

What is a trough in a wave?

• A trough is the highest point of a wave.

• A trough is the lowest point of a wave.

• A trough is the distance between two waves.

• A trough is the speed of a wave.

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 the rest position.

• The frequency of a wave measured in hertz.

What is echolocation?

• A method used by some animals to locate objects by reflecting sound waves off them.

• A technique for measuring distances using light.

• A way for animals to communicate using visual signals.

• A process of navigating using the Earth's magnetic field.

What is the relationship between frequency and wavelength?

• Frequency and wavelength are directly related; as frequency increases, wavelength increases.

• Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

• Frequency and wavelength have no relationship; they are independent of each other.

• Frequency and wavelength are equal; they represent the same physical quantity.

What is a mechanical wave?

• A wave that can travel through a vacuum without a medium.

• A wave that requires a medium to travel through, such as sound waves.

• A wave that is produced by electromagnetic fields.

• A wave that only travels in liquids.

What is a transverse wave?

• A wave in which the motion of the medium is parallel to the direction of the wave.

• A wave that travels through a vacuum without a medium.

• A wave in which the motion of the medium is perpendicular to the direction of the wave.

• A wave that can only travel through solids.

What is a longitudinal wave?

• A wave in which the motion of the medium is perpendicular to the direction of the wave.

• A wave that travels through a vacuum without a medium.

• A wave in which the motion of the medium is parallel to the direction of the wave.

• A wave that only travels in one direction.

What is a peak in a wave?

• A trough in a wave.

• The highest point of a wave.

• The lowest point of a wave.

• A point where the wave starts to decrease.

What are sound waves?

• Sound waves are vibrations that travel through air, water, or solid materials and can be heard when they reach a person's or animal's ear.

• Sound waves are static waves that do not require a medium to travel.

• Sound waves are electromagnetic waves that can travel through a vacuum.

• Sound waves are high-frequency vibrations that can only be heard by certain animals.
