Question

multiple choice 7.15 points
consider the four different transverse waves in the image. assume the waves are all traveling at the same speed and read the paragraph.
wave a has the same frequency as wave _. wave b has the same amplitude as wave _. the wave with the shortest wavelength is wave ___.
which letters, in order of appearance, best complete the sentences?
b, a, d
c, a, b
c, a, d
b, c, d

Explanation:

Step1: Determine frequency

Frequency is the number of waves per unit time. Waves with the same frequency have the same number of crests (or troughs) in a given length. Wave A and wave C have the same number of crests in the given length, so wave A has the same frequency as wave C.

Step2: Determine amplitude

Amplitude is the maximum displacement from the rest position. Wave B and wave A have the same height (amplitude).

Step3: Determine wavelength

Wavelength is the distance between two consecutive crests (or troughs). The shorter the distance between crests (or troughs), the shorter the wavelength. Wave D has the shortest distance between consecutive crests (or troughs), so wave D has the shortest wavelength.

Answer:

C. A. D
