So what type of wave is sound? Sound waves fall into three categories: longitudinal waves, mechanical waves, and pressure waves. Keep reading to find out what qualifies them as such. Longitudinal Sound Waves - A longitudinal wave is a wave in which the motion of the medium’s particles is...
The loudness of a sound depends on the amplitude of the sound wave. The pitch depends on its frequency. 2. The sensation produced in the organs of hearing by waves of this type. See Note at ultrasound. Did You Know? The form of energy called sound is produced when matter moves or ...
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/...

Sound, a mechanical disturbance from a state of equilibrium that propagates through an elastic material medium. A purely subjective, but unduly restrictive, definition of sound is also possible, as that which is perceived by the ear. Learn more about the
Learn what sound waves are. Review the different types of sound waves. Understand what type of a wave a sound wave is and see how a sound wave is...
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 Y the marked distance corresponding to the wavelength of the...
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 ...
