Across
  1. 4. The highest points of a transverse wave, where the displacement is at maximum positive amplitude.
  2. 6. The maximum displacement of a wave or oscillating object from its equilibrium position, measured in meters (m). It represents the wave's intensity or energy.
  3. 8. Motion‌: A motion that repeats itself at regular intervals, such as the swinging of a pendulum or the vibration of a tuning fork.
  4. 9. (Hz)‌: The SI unit of frequency, defined as one cycle per second (1 Hz = 1 s⁻¹).
Down
  1. 1. A disturbance that travels through a medium or space, transferring energy without transferring matter. Waves can be transverse (e.g., light) or longitudinal (e.g., sound).
  2. 2. (f)‌: The number of cycles or oscillations per unit time, measured in hertz (Hz). It is related to period by f = 1/T.
  3. 3. One complete round trip or oscillation of a periodic motion, from start to finish and back to the starting point.
  4. 5. The lowest points of a transverse wave, where the displacement is at maximum negative amplitude.
  5. 7. (T)‌: The time taken for one complete cycle of a periodic motion, measured in seconds (s). It is the reciprocal of frequency (T = 1/f).
