waves and wave properties

Front

What is the formula to calculate the frequency of a wave?

Back

Frequency (f) = Speed (v) / Wavelength (λ)

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points in phase on a wave, such as crest to crest or trough to trough.

Front

What is the speed of a wave if its frequency is 10 Hz and its wavelength is 5 m?

Back

Speed = Frequency x Wavelength = 10 Hz x 5 m = 50 m/s.

Front

What are the two main types of waves?

Back

Transverse waves and longitudinal waves.

Front

What characterizes a transverse wave?

Back

Transverse waves have crests and troughs, with particle motion perpendicular to wave direction.

Front

What characterizes a longitudinal wave?

Back

Longitudinal waves have compressions and rarefactions, with particle motion parallel to wave direction.

Front

What is amplitude in a wave?

Back

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

Front

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 relationship between wavelength and frequency?

Back

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

Front

What is a compression in a longitudinal wave?

Back

A compression is a region in a longitudinal wave where particles are closest together.
