  1. Question 1

    In a skipping rope being shaken, 6 complete waves fit into 12 cm. What is the wavelength?

    Answercm

  2. Question 2

    A guitarist plucks a string harder. What changes in the sound wave?

    • A. The wavelength becomes zero.
    • B. The wave stops.
    • C. The amplitude gets bigger, so the sound is louder.
    • D. The amplitude gets smaller.
