Waves & Wave Properties

What is the definition of a wave?

• A wave is a disturbance that transfers energy from one place to another without transferring matter.

• A wave is a continuous movement of particles in a medium.

• A wave is a static position of particles in a medium.

• A wave is a type of sound that cannot travel through a vacuum.

What is the Doppler effect?

• The change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source.

• The phenomenon where sound waves are amplified when they pass through a medium.

• The increase in speed of a wave as it travels through a vacuum.

• The reflection of waves off a surface causing a change in direction.

What are the two main types of waves?

• Mechanical waves and electromagnetic waves.

• Sound waves and light waves.

• Transverse waves and longitudinal waves.

• Radio waves and seismic waves.

What is a mechanical wave?

• A wave that requires a medium (solid, liquid, or gas) to travel through.

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

• A wave that is produced by electromagnetic fields.

• A wave that only travels through solids.

What is a transverse wave?

• A wave in which the particles of the medium move parallel to the direction of the wave's propagation.

• A wave in which the particles of the medium move perpendicular to the direction of the wave's propagation.

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

• A wave that can only travel through solid materials.

What is the amplitude of a wave?

• The amplitude is the maximum displacement of points on a wave from the rest position.

• 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 measured in meters.

What is the wavelength of a wave?

• The distance between two consecutive points that are in phase on a wave, such as crest to crest or trough to trough.

• The speed of the wave divided by its frequency.

• The amplitude of the wave measured from the rest position.

• The total distance traveled by the wave in one complete cycle.

What is the crest of a wave?

• The lowest point of a transverse wave.

• The highest point of a transverse wave.

• The point where the wave begins to break.

• The distance between two crests.

What is an electromagnetic wave?

• A wave that requires a medium to travel

• A wave that can travel through a vacuum and does not require a medium

• A sound wave that travels through air

• A wave that is only visible to the human eye

What is wave speed?

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

• The speed at which sound travels in air.

• The rate at which light travels in a vacuum.

• The speed of a moving object in a straight line.
