What is the frequency of a sound wave with a period of 0.02 seconds? A. 20 Hz B. 50 Hz C. 100 Hz D. 200 Hz 相关知识点: 试题来源: 解析 B。频率等于周期的倒数,周期为 0.02 秒,频率 = 1/0.02 = 50Hz,所以选择 B 选项。反馈 收藏 ...
∙8yago Best Answer The frequency of a wave can be calculated using the formula f = 1/T, where f represents frequency and T represents period. In this case, with a period of 6 seconds, the frequency would be f = 1/6 = 0.1667 Hz. This means that the wave completes 0.1667 cy...

3. A frequency is the number of oscillations in alternating electrical current each second.4. The term frequency may also refer to cycles per second of an electromagnetic wave, such as a sound wave or a light wave. The frequency of light determines its color, as seen by the human eye. ...

Period = The time required to produce one complete cycle of a waveform. At its most basic, frequency is how often something repeats. In the case of electrical current, frequency is the number of times a sine wave repeats, or completes, a positive-to-negative cycle. The more cycles that ...
