What is a wave?

Back

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

Front

What are the two main types of waves?

Back

Mechanical waves and electromagnetic waves.

Front

What is the definition of frequency in relation to waves?

Back

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

What is amplitude in a wave?

Back

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

What is the difference between longitudinal and transverse waves?

Back

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

Front

What happens to the pitch of a sound wave when its frequency increases?

Back

The pitch becomes higher.

What is the relationship between amplitude and loudness in sound waves?

Back

Higher amplitude means louder sound, while lower amplitude means softer sound.

What is refraction in the context of waves?

Back

Refraction is the bending of waves as they pass from one medium to another due to a change in speed.
