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 ...
解析 The frequency of a progressive wave is the number of cycles of the wave that pass a fixed point per unit time. 频率是指单位时间内波形重复的次数。对于进行波来说,频率指的是单位时间内波形经过某一点的次数。 简而言之,频率代表了波的振动速度,它决定了波的音调或颜色。

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 cycles in one second. ...

Next, we have the period, which is the time, in seconds, that it takes for one full wave cycle to pass a particular point. We can think of the period as the number of seconds per cycle. The reciprocal of the period is called the frequency. The frequency, in Hertz, is ...
Define the � frequency’ and � time period’ of a wave What is the relation between the two - Frequency: Number of cycles or vibration in one second is known the frequency. SI unit of frequency is $per second$ and it is also written as $Hz$.Time pe
Wave speed, wavelength and frequency: The speed of propagation of a wave is related to its wavelength and frequency by the relation; $$\boxed{v = \lambda f} $$, where {eq}v {/eq} is the wave speed {eq}f {/eq} is the freque...
