select the correct answer. andrew shakes a rope, and the rope makes a wave as shown. andrew asks his sister to shake the rope so the wavelength of the wave decreases. which diagram shows the correct wave that his sister makes? a. b. c. d.
Answer
Answer:
C.
Explanation:
Step1: Recall wavelength definition
Wavelength is distance between two - consecutive identical points on a wave.
Step2: Analyze wave diagrams
A decrease in wavelength means the waves are closer together. Diagram C has waves that are more closely spaced compared to the original wave and the other options, indicating a shorter wavelength.
