A. volume B. speed C. frequency D. intensity 相关知识点: 试题来源: 解析 C。解析:A high-frequency sound has a high pitch, while a low-frequency sound has a low pitch. 高频声音音调高,低频声音音调低,所以声音的音调由频率决定。反馈 收藏 ...
Every sound has a pitch(音高).The pitch of a sound is how high or how low the sound is.Study the graph.Each bar(条形图)shows the lowest pitch to the highest pitch heard.The numbers arc given in a measurement called hertz(赫兹).Pitches over 20,000 hertz are too high for humans to ...

The form of energy called sound is produced when matter moves or vibrates. The vibrations are transferred to another medium, usually the air, and travel through it as sound waves. You hear a sound when its vibrations reach your eardrum, causing it to vibrate. The pitch of a sound is dire...
Answer to: Fill in the blank(s) with the correct word. The pitch or tone of a sound is due to the number of waves per second, which is called...
During an experiment on sound waves, which property determines the pitch of a sound? A. Frequency B. Amplitude C. Wavelength D. Speed 相关知识点: 试题来源: 解析 A。频率决定声音的音调。B 选项振幅决定声音的响度;C 选项波长和 D 选项速度不是决定音调的主要因素。
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,不是影响音调的主要因素;虽然波长(Wavelength of the sound wave)与频率有关系,但直接影响音调的...
The ( ) refers to the change in pitch of a sound due to the motion either of the source or of the listener. If they are approching each other, the pitch is higher; If they are moving apart, the pitch is lower. A. Doppler effect B. beats C. sound level D. interference 相关...
