21 A wave moves along the surface of water.What is the wavelength of the wave? A A the distance between one crest and the next crest B the distance that a crest moves along the surface in one second C the distance that a particle of water moves up and down D the number of waves ...
A. The speed of the wave B. The frequency of the wave C. The wavelength of the wave D. The amplitude of the wave 相关知识点: 试题来源: 解析 D。当波在固定端反射时,波的振幅会发生变化。选项 A,波速不变。选项 B,频率不变。选项 C,波长不变。反馈...
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 wave.[1](ii) State what happens to the amplitude and the wavelength of the wave if1. the loudness of...
In an experiment on wave interference, the measured fringe spacing is smaller than the theoretical value. Which of the following might be the reason? A. The wavelength of the light was measured as longer than it actually is B. The distance between the slits was measured as shorter than it ...
A wave has height, from low point to high point,可知答案为D项说明的内容是错误的,故选B3.根据文章内容第三段的内容If we want to find the speed of a wave, we may use the following way : Speed =" wavelength" × frequency (频率).根据题目中所给的信息,可知答案为D4.根据文章整体的内容和...
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 number...
Speed of the sound wave D. Wavelength of the sound wave 相关知识点: 试题来源: 解析 B。解析:在声波实验中,声音的音调主要由声波的频率(Frequency of the sound wave)决定。声波的振幅(Amplitude of the sound wave)主要影响声音的响度;声音在特定介质中的速度(Speed of the sound wave)是相对固定的,不...

9 The wavelength of a progressive wave is defined as the distance between adjacent points on the wave which C A have the same displacement. B have the same amplitude. C are in phase. D are in antiphase. 相关知识点: 试题来源: 解析 CA-not a correct descriptionB-not a correct description...
of water that make up a wave actually moved across the sea, sailing would be impossible. If we want to find the speed of a wave we may use the following way: Speed=wavelength X frequency Here, wavelength is the distance between two high points(crests), frequency means the number of ...
