Asked by Zephyr Benedict

D. Frequency

Answered by GPT-5 mini AI
C. Wavelength

Reason: Moving the holders closer shortens the distance available for each cycle, so the distance between successive crests (the wavelength) decreases. Frequency (hand motion) and wave speed (set by rope tension and mass per length) remain essentially unchanged.
