What is a wave?

Back

A wave is a disturbance that transfers energy through space or a medium, without transferring matter.

What are the two main types of waves?

Back

Transverse waves and longitudinal waves.

Front

Describe the motion of particles in a transverse wave.

Back

Particles move perpendicular to the direction of the wave's motion.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is amplitude?

Back

Amplitude is the maximum displacement of a point on a wave from its rest position.

What is frequency?

Back

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

How does frequency relate to pitch in sound waves?

Back

Higher frequency results in a higher pitch, while lower frequency results in a lower pitch.

Front

What is the speed of a wave?

Back

Wave speed is the distance a wave travels per unit of time, calculated as speed = wavelength × frequency.

Can sound waves travel through a vacuum?

Back

No, sound waves require a medium (solid, liquid, or gas) to travel.

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as one increases, the other decreases.
