Question

A periodic wave is produced by a vibrating

tuning fork. The amplitude of the wave would be
greater if the tuning fork were
(1) struck more softly
(2) struck harder
(3) replaced by a lower frequency tuning fork
(4) replaced by a higher frequency tuning fork

Answer 1

The amplitude of a wave from a vibrating tuning fork is greater when the tuning fork is struck harder. Frequency modifications and how softly the fork is struck do not increase the amplitude.

Step-by-step explanation:

The amplitude of a wave produced by a vibrating tuning fork would be greater if the tuning fork were struck harder. The amplitude of a wave corresponds to how much energy it carries, which is directly affected by the force applied to the tuning fork. The other options, such as frequency modifications or striking it more softly, would not increase the amplitude. The frequency of the tuning fork, whether higher or lower, does not affect the amplitude directly; it instead dictates the pitch of the sound. Therefore, the loudest sound from a tuning fork occurs when it resonates at the natural frequency of the air column in a tube, creating a standing wave and constructive interference.

Answer 2

The amplitude of the wave would be greater if the tuning fork were "struck harder" since this would make for a louder noise, which happens from higher amplitudes.
