Wave characteristics PS4-1

Front

What is the definition of wave frequency?

Back

Wave frequency is the number of times a wave completes a cycle in one second, measured in Hertz (Hz).

Front

What is the relationship between frequency and pitch in sound waves?

Back

Higher frequency waves produce higher pitched sounds, while lower frequency waves produce lower pitched sounds.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

What is wavelength?

Back

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

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that points on a wave move from their rest position, indicating the wave's energy.

Front

How does wavelength affect sound?

Back

Longer wavelengths correspond to lower frequencies and lower pitches, while shorter wavelengths correspond to higher frequencies and higher pitches.

Front

What is the formula to calculate wave speed?

Back

Wave speed = frequency × wavelength.

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium to travel through, while electromagnetic waves do not.

Front

What is an example of a mechanical wave?

Back

Sound waves are an example of mechanical waves.
