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
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。
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...
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...
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...
Wavelength and Frequency:The wavelength of a wave describes its periodicity in space. It is the minimum distance traveled by the wave before its shape begins to repeat. Frequency is another parameter used to describe waves. It is defined as the numbe...
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{\...

Although not statistically significant; low frequency application may be more advantageous than intermediate as lower number of high energy shock waves required which may cause less tissue damage. On the other hand, despite lack of a statistically significant difference, relatively longer anesthesia time...
