1、There is a sound wave,the frequency of the wave f=440Hz,and the velocity V=340m/s,Find the wavFind the wave length of the sound wave? 相关知识点: 试题来源: 解析 楼主,这个题的意思是:有个声波,频率为440赫兹,速度为340赫兹,求波长.波长(那个符号我打不出来)=V*T(周期)=V/f=340/...
All frequency sound generator tools in one app! Tone generation, sound tests, musical tuning and many more. This app helps if you are looking for generating sou…
PURPOSE: A sound wave escapement device is provided to generate the optimum frequency appropriate for an application object and to improve an escapement effect by changing a wave sound frequency through simple manipulation. CONSTITUTION: A sound wave escaping device is made up of a driver(11) for...
The amplitude, or height of the sound wave determines its loudness. The wavelength is the distance between two waves and affects the wave's frequency. Frequency determines the pitch of the sound. A higher frequency means a higher pitched sound....
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 ...
using vibrates, which then disturbs particles in the air. The disturbed air particles subsequently disturb the ones next to them, and the ones next to those, on so on. What you get is a domino effect of air particles bumping into each other hence the term frequency of the sound wave. ...
