characteristics of waves: part 1
waves are patterns of motion that carry energy from one place to another. some examples of waves include sound waves, water waves, and light waves. a simple wave has a repeating pattern with a specific wavelength, frequency, and amplitude.
the amplitude of a wave is how far it dips down and rises up from its resting position. in this example, the amplitude is 4 centimeters.
the wavelength of a wave is the distance between two consecutive crests or two consecutive troughs. in this example, the wavelength is 6 centimeters.
the frequency of a wave is the number of wavelengths that pass a given point in a certain amount of time. if two waves are traveling at the same speed, the wave with the smaller wavelength has the greater frequency.
answer the questions below. you can assume that the waves in each set are traveling at the same speed.

1. wave a wave b

which wave has the greater amplitude?

1. wave c wave d

which wave has the greater wavelength?

Explanation:

Step1: Recall amplitude definition

Amplitude is the maximum displacement from the resting - position.

Step2: Compare amplitudes of Wave A and Wave B

Wave A has an amplitude of 4 cm (from the graph, maximum displacement from equilibrium is 4 cm). Wave B has an amplitude of 5 cm (from the graph, maximum displacement from equilibrium is 5 cm). So Wave B has a greater amplitude.

Step3: Recall wavelength definition

Wavelength is the distance between two consecutive crests or troughs.

Step4: Compare wavelengths of Wave C and Wave D

Wave C has a smaller distance between consecutive crests compared to Wave D. So Wave D has a greater wavelength.

Answer:

1. Wave B
2. Wave D
