Exploring Waves: Properties and Types

What is the definition of a wave?

• A wave is a stationary disturbance that remains in one place.

• A wave is a disturbance that travels through space and matter, transferring energy.

• A wave is a solid object that does not move.

• A wave is a type of particle that cannot transfer energy.

List three properties of waves.

• direction

• phase

• speed

• Wavelength, frequency, amplitude

What is the difference between amplitude and wavelength?

• Amplitude is the distance between two crests, while wavelength is the height of the wave.

• Amplitude refers to the frequency of the wave, and wavelength is the speed of the wave.

• Amplitude is the total energy of the wave, while wavelength is the time period of the wave.

• Amplitude is the height of the wave, while wavelength is the distance between two consecutive crests.

How does frequency relate to wave speed?

• Frequency is inversely proportional to wave speed when wavelength is constant.

• Frequency is directly proportional to wave speed when wavelength is constant.

• Increasing frequency decreases wave speed when wavelength is constant.

• Wave speed is independent of frequency and wavelength.

What is the formula for calculating wave speed?

• wave speed = amplitude × frequency

• wave speed = wavelength / time

• wave speed = frequency + wavelength

• wave speed = frequency × wavelength

Define a mechanical wave.

• A mechanical wave does not require a medium to propagate.

• A mechanical wave is a type of electromagnetic wave.

• A mechanical wave is a wave that requires a medium to travel through.

• A mechanical wave can travel through a vacuum.

What are the two main types of mechanical waves?

• Surface waves and seismic waves

• Sound waves and light waves

• Transverse waves and longitudinal waves

• Mechanical waves and electromagnetic waves

Give an example of a transverse wave.

• Seismic P-waves

• Water waves

• Light waves

• Sound waves

What is a longitudinal wave?

• A longitudinal wave is a wave that travels through a vacuum without any medium.

• A longitudinal wave is a wave where particle displacement is parallel to wave direction.

• A longitudinal wave is a wave that only travels in one direction without oscillation.

• A longitudinal wave is a wave where particle displacement is perpendicular to wave direction.

Describe the motion of particles in a longitudinal wave.

• Particles in a longitudinal wave move perpendicular to the direction of wave propagation.

• Particles in a longitudinal wave move parallel to the direction of wave propagation.

• Particles in a longitudinal wave remain stationary while the wave travels.

• Particles in a longitudinal wave oscillate in a circular motion.
