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 ...
A wave is a physical phenomenon characterized by an oscillating disturbance that moves through space. A wave can be described, mathematically, by a periodic function such as sine function. The sine function description has parameters such as amplitude, wavelength, frequency and phase angle which ...
<p>To answer the question about the difference between a sound wave and a TV wave, we can break down the explanation into clear steps:</p><p>1. <strong>Define Sound Waves</strong>: - Sound waves are mechanical waves that require a medium (like air, w

Sound Wavelength:The most important characteristic of sound waves may be the wavelength. Sound consists of a longitudinal wave that includes compressions and rarefactions as they travel through a given medium. The distance that one wave travels before it repeats itself is the wavelength. It is the...
A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water or any other liquid orsolidmatter) as it propagates away from the source of the sound. Sound waves are created by object vibrations and producepressure waves, for exam...

What type of waves are sound waves ? View Solution Diagnostic ultrasound of frequency 3.80 MHz is used to examine tumors in soft tissue. (a) What is the wavelength in air of such a sound wave? (b) If the speed of sound in tissue is 1500 m/s, what is the wavelength of this wave ...
Explain the term, energy density, and intensity of wave. What is meant by the polarization of light? What is a Wave-Particle Duality? What is the wave-particle duality? What are the basic properties that a medium must possess to have the propagation of a mechanical wave?
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...
