Across
- 2. (Hz): The SI unit of frequency, defined as one cycle per second (1 Hz = 1 s⁻¹).
- 6. (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).
- 8. One complete round trip or oscillation of a periodic motion, from start to finish and back to the starting point.
- 9. The highest points of a transverse wave, where the displacement is at maximum positive amplitude.
Down
- 1. 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. A phenomenon where a system oscillates with greater amplitude at certain frequencies (resonant frequencies) when driven by an external force at or near its natural frequency. Examples include the shattering of a glass by sound waves at its resonant frequency.
- 4. The lowest points of a transverse wave, where the displacement is at maximum negative amplitude.
- 5. (f): The number of cycles or oscillations per unit time, measured in hertz (Hz). It is related to period by f = 1/T.
- 6. Motion: A motion that repeats itself at regular intervals, such as the swinging of a pendulum or the vibration of a tuning fork.
- 7. 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).
