Copy the table and complete it by writing transverse and longitudinal in the correct boxes in the first column. Transverse describes a wave that varies from side to side, at right angles to the direction of travel. Longitudinal describes a wave that varies back and forth along the direction of travel. Note: Ripples on water is an example of transverse wave. Sound wave is the example of longitudinal wave.

Look at the wave shown. The horizontal and vertical scales are in cm . What is its wavelength?

The wavelength of a wave is the distance between any two corresponding points on adjacent waves. It is easiest to visualise the wavelength of a wave as the distance from one wave crest to the next. The wavelength from the above graph is 4 cm .

Look at the wave shown. The horizontal and vertical scales are in cm . What is its amplitude?

The amplitude from the above graph is 3 cm . Amplitude is generally calculated by looking at a graph of a wave and measuring the height of the wave from the resting position. The amplitude is a measure of the strength or intensity of the wave. For example, when looking at a sound wave, the amplitude will measure the loudness of the sound.

Look at the wave shown. The horizontal and vertical scales are in cm If this wave is moving at a speed of 10 cm s - 1 , what is its frequency?

Given: The speed of wave v = 10 cm s - 1 , The wavelength of the wave from the above graph ( λ ) = 4 cm Frequency (f) =? To find the frequency we know the relation v = f λ = f = v λ By substituting the values f = 10 4 = 2 . 5 Hz .
