Waves Unit Part 1: Wave Properties

Front

What is the definition of wavelength?

Back

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

Front

What is the SI unit for measuring frequency?

Back

The SI unit for frequency is hertz (Hz).

Front

What is the crest of a wave?

Back

The crest is the highest point of a wave.

Front

What does frequency measure in terms of waves?

Back

Frequency measures the number of wavelengths that pass a point each second.

Front

What are transverse waves?

Back

Transverse waves are waves that carry energy at a right angle or perpendicular to the direction of energy flow.

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum distance that points on a wave move from their rest position.

Front

What is the trough of a wave?

Back

The trough is the lowest point of a wave.

Front

How is the speed of a wave calculated?

Back

The speed of a wave is calculated by multiplying its frequency by its wavelength (Speed = Frequency x Wavelength).

Front

What is the relationship between frequency and period?

Back

Frequency is the inverse of the period; as frequency increases, the period decreases (Frequency = 1/Period).

Front

What are longitudinal waves?

Back

Longitudinal waves are waves in which the particle displacement is parallel to the direction of wave propagation.
