Waves problems 1

Front

What is a wave?

Back

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

Front

What are sound waves?

Back

Sound waves are longitudinal waves that are created by vibrating objects and travel through a medium such as air, water, or solids.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points of the same phase in a wave, such as crest to crest or trough to trough.

Front

What is amplitude?

Back

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

Front

What is frequency?

Back

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

Front

What is the relationship between frequency and wavelength?

Back

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

Front

What is the period of a wave?

Back

The period is the time it takes for one complete wave cycle to pass a given point, measured in seconds.

Front

How do sound waves travel?

Back

Sound waves travel by compressing and rarefying the particles in the medium they move through.

Front

What happens to sound waves as they move away from the source?

Back

As sound waves move away from the source, they spread out and their amplitude decreases, causing the sound to weaken.

Front

What is the difference between longitudinal and transverse waves?

Back

In longitudinal waves, the particle displacement is parallel to the direction of wave propagation, while in transverse waves, the displacement is perpendicular.
