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 cyc
A There is no phase difference.BThey are out of phase by a quarter of a cycle.C They are out of phase by half a cycle.DThey are out of phase by 0.8 of a cycle. 相关知识点: 试题来源: 解析 B First, we need to find the wavelength of the wave using the wave speed formula . Th...
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。
Alternating current (ac) frequency is the number of cycles per second in an ac sine wave. Frequency is the rate at which current changes direction per second. Frequency is measured in hertz (Hz), an international unit of measure where 1 hertz is equal to 1 cycle per second. Hertz (Hz...
1. A sound wave of the form s = sm cos(kx - ωt + φ) travels at 345 m/s through air in a long horizontal tube. At one instant, air molecule A at x = 2.00 m...
For example, very low frequency radio waves can be detected with a special type of radio receiver called a very low frequency radio or VLF radio, which can pick up radio waves with very low frequencies, from 3 to 30 kilohertz, which aren't really picked up by a regular household or car...
Frequency of Wave: The frequency {eq}(\upsilon) {/eq}, wavelength {eq}(\lambda) {/eq} of electromagnetic radiation and the speed of the light {eq}(c) {/eq} are related to each other as given below: {eq}\upsilon = \frac{\...
The frequency of the wave can be calculated if the angular speed of the wave is given. The wave's frequency is the ratio of the wave's angular speed and the two times of the pi-value. The frequency of the wave's unit is {eq}{\rm{Hz}} {/e...

试题来源: 解析 The frequency of the water wave remains constant as it passes into the slower region. 当水波从一个介质进入另一个传播速度较慢的介质时,其频率保持不变。这是因为频率由波源决定,与介质无关。波速的降低会导致波长的减小,以保持频率恒定。因此,水波的频率在进入较慢的区域后保持不变。
