Question

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

Explanation:

The wavelength is the distance between two consecutive points in phase (e.g., two crests or two troughs), and 1 correctly represents this. The amplitude is the maximum displacement from the equilibrium position, and 3 correctly shows this. The crest is the highest - point of the wave, but there is no '4' labeled in the diagram. Since there is no '4' to be the crest as stated in option B, it is incorrect.

Answer:

B. 4 is the crest and 1 is the wavelength
