The intensity of a sound wave is: a) Amplitude b) Tone c) Frequency d) None of the above Frequency is to pitch as amplitude is to a. compression. b. rarefaction. c. tone. d. loudness. Fill in the blank(s) with the cor...
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 ...
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 ...
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 ...
A wave form pattern of a pure tone is: a) Sine wave b) Oscillating wave c) Pure wave d) Threshold wave The intensity of a sound wave is: a) Amplitude b) Tone c) Frequency d) None of the above As the decibels of a sound increase, the:...
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/...
答案:A。“以……频率振动”用 at a certain frequency,固定搭配。in 表示“在……里面”;on 表示“在……上面”;with 表示“和……一起”,均不符合题意。 We have done some experiments to study the properties of waves. In one experiment, we used a slinky to create a wave. We observed how ...
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 ...
aVELOCITY OF SOUND. The velocity of sound through a continuous material medium, also called the acoustical velocity, is the velocity of a very small compression-rarefaction wave moving adiabatically and frictionlessly through the medium. Thermodynamically, the motion of a sound wave is a constant-en...
What is a Sound Wave? A sound wave is caused by energy that moves through air, water or other materials as tiny vibrations. For example, when an object like a cell phone vibrates, it creates a disturbance, which propagates as a sound wave. Properties of a Sound Wave The five main cha...
