Wave Properties

Front

What is the definition of a wave?

Back

A wave is a disturbance that transfers energy through space or matter, typically characterized by its frequency, wavelength, and amplitude.

Front

What is frequency in the context of waves?

Back

Frequency is the number of cycles of a wave that pass a given point in one second, measured in hertz (Hz).

Front

How is wavelength defined?

Back

Wavelength is the distance between two consecutive points that are in phase on a wave, such as from crest to crest or trough to trough.

Front

What is amplitude in wave properties?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, which is related to the energy of the wave.

Front

What is the relationship between energy and amplitude in waves?

Back

Higher amplitude waves carry more energy, while lower amplitude waves carry less energy.

Front

What distinguishes longitudinal waves from transverse waves?

Back

In longitudinal waves, particles of the medium move parallel to the direction of wave propagation, while in transverse waves, particles move perpendicular to the direction of wave propagation.

Front

What is a compression in a longitudinal wave?

Back

A compression is a region in a longitudinal wave where particles are packed closely together, resulting in higher pressure.

Front

What is a rarefaction in a longitudinal wave?

Back

A rarefaction is a region in a longitudinal wave where particles are spread apart, resulting in lower pressure.

Front

How does the speed of a wave relate to its frequency and wavelength?

Back

The speed of a wave is equal to the product of its frequency and wavelength (Speed = Frequency x Wavelength).

Front

What is the formula for calculating wave speed?

Back

Wave speed (v) can be calculated using the formula v = f × λ, where f is frequency and λ is wavelength.
