Properties of waves

Front

What is the definition of wavelength?

Back

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

Front

What does amplitude measure in a wave?

Back

Amplitude measures the height of the wave from its rest position to its crest or trough.

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What is a wave crest?

Back

A wave crest is the highest point of a wave.

Front

What is a wave trough?

Back

A wave trough is the lowest point of a wave.

Front

What is the formula for wave speed?

Back

Wave speed = Wavelength x Frequency.

Front

What type of wave requires a medium to travel through?

Back

Mechanical waves require a medium (solid, liquid, or gas) to travel through.

Front

What is an example of a transverse wave?

Back

An example of a transverse wave is a wave on a string or electromagnetic waves.

Front

What is an example of a longitudinal wave?

Back

An example of a longitudinal wave is a sound wave.

Front

What is the principle of superposition in wave theory?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave is the sum of the individual waves.
