Question

refer to the diagram above. which of the following is labeled incorrectly? a 3 is the amplitude and 2 is the trough b 4 is the crest and 1 is the wavelength c 1 is the wavelength and 2 is the crest d 1 is the wavelength and 3 is the amplitude

Explanation:

The crest of a wave is the highest - point, the trough is the lowest - point, the wavelength is the distance between two consecutive identical points (e.g., two crests or two troughs), and the amplitude is the maximum displacement from the equilibrium position. In option C, 2 is the trough, not the crest.

Answer:

C. 1 is the wavelength and 2 is the crest
