This chapter reviews various measurement techniques for sound intensity, recording and reproduction, and the Doppler effect. The intensity of a sound wave at any point is defined as the energy per second that is carried across unit area normal to the direction of travel of the wave at that ...
6 (a)Fig. 6.1 represents the waveform of a sound wave. The wave is travelling at constant speed.displacement of particles distance along wave Fig.6.1(i) On Fig. 6.1,1. label with the letter X the marked distance corresponding to the amplitude of the wave,[1]2. label with the letter ...
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 ...
13. (intr) (of a sound) to be heard 14. (intr) to resonate with a certain quality or intensity: to sound loud. 15. (copula) to give the impression of being as specified when read, heard, etc: to sound reasonable. 16. (tr) to pronounce distinctly or audibly: to sound one's...
In one experiment, we used a slinky to create a wave. We observed how the wave propagated and reflected at the ends of the slinky. We also measured the wavelength and frequency of the wave. The wavelength is the distance between two consecutive crests or troughs of a wave. The frequency...
Based on the figure, does S depend on the frequency of a sound wave of a given intensity? A. Yes, because as frequency increases, S increases. B. Yes, because as frequency increases, S remains constant. C. No, because as frequency increases, S increases. D. No, because as frequency ...
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/...
