Waves

What is the relationship between wavelength and frequency?

• Wavelength and frequency are directly related; as the wavelength increases, the frequency also increases.

• Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

• Wavelength and frequency are unrelated; changes in one do not affect the other.

• Wavelength and frequency are equal; they have the same numerical value.

What is a wave?

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

• A wave is a solid object that moves through space.

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

• A wave is a stationary phenomenon that does not involve energy transfer.

Why can't sound travel in outer space?

• Sound can travel through a vacuum.

• Sound requires a medium to travel through; in outer space, there is no medium.

• Sound travels faster in space than in air.

• Sound can travel through light waves.

What is a longitudinal wave?

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

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

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

• A wave that oscillates in multiple dimensions.

What is the speed of light in a vacuum?

• Approximately 150,000 kilometers per second

• Approximately 299,792 kilometers per second

• Approximately 400,000 kilometers per second

• Approximately 250,000 kilometers per second

What are the two main types of mechanical waves?

• Transverse waves and longitudinal waves.

• Sound waves and light waves.

• Radio waves and microwaves.

• Surface waves and seismic waves.

What is an electromagnetic wave?

• A wave that can travel through matter and empty space, consisting of oscillating electric and magnetic fields.

• A type of wave that only travels through solid materials.

• A wave that is produced by sound vibrations in the air.

• A wave that can only exist in a vacuum without any medium.

What is wave energy?

• The energy carried by a wave, which is related to its amplitude and frequency.

• The energy produced by sound waves in the air.

• The energy generated by the movement of tectonic plates.

• The energy stored in the gravitational field of the Earth.

What is wave frequency?

• The speed at which waves travel through a medium.

• The number of complete waves that pass a given point in a certain amount of time, usually measured in Hertz (Hz).

• The amplitude of the waves measured in decibels (dB).

• The wavelength of the waves measured in meters.

What is amplitude in a wave?

• The distance between two consecutive crests of a wave.

• The maximum displacement of points on a wave from its rest position, indicating the energy of the wave.

• The frequency of the wave measured in hertz.

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