A. Sound waves can travel in a vacuum. B. Sound waves are transverse waves. C. The speed of sound waves is constant. D. Sound waves need a medium to travel. 相关知识点: 试题来源: 解析 D。本题考查声音传播的条件。声音的传播需要介质,不能在真空中传播,A 选项错误;声音是纵波,B 选项错误...
When a wave is created, the distance between one compression and the next compression is called the wavelength. The faster the sound waves pass a given point, the shorter the wavelength and the higher the frequency. Sounds of all frequencies travel at the same rate in the same medium. (Soun...
What can we infer about sound waves? A. They can travel through a vacuum. B. They travel faster in air than in water. C. They are a form of electromagnetic radiation. D. They need a medium to travel. 相关知识点: 试题来源:
Does sound need a medium to travel? Yes, sound needs a medium to travel. It can travel through any medium, but it cannot travel through a vacuum. Sound is absent in outer space, as there is no medium to carry sound vibrations. When the vibrations are fast, you hear a high note, and...
wave when it passes over from one medium to another. The phenomenon is most noticeable in light waves and is rarely seen in sound waves, as they tend to travel through a single medium (air). Nevertheless, sound waves get refracted when wavefronts travel in a medium with varying pr...
An article about sound waves mentions that sound travels through different mediums. Which medium does sound travel fastest through? A. Air B. Water C. Steel D. Wood 相关知识点: 试题来源: 解析 C。解析:声音在固体中传播速度最快,在钢铁中传播速度比在空气、水和木材中都快。需了解声音在不同...
Certainly the sound could travel because what is known as "particle interaction" allows the vibrating wave to be transported from one location to another. However, ultimately, the mechanical sound waves need a receiver in order to complete their journey. And although there may be a body present...
If the inclusions are resonators that respond equally to the influence of waves coming from different directions, then the effective density of the medium in a certain frequency band becomes negative. If the direction of the dipole moment of the resonators is fixed, then the medium with ...
Longitudinal waves cause the medium to vibrate parallel to the direction of wave propagation, while transverse waves cause the medium to vibrate perpendicular to the direction of wave propagation. Sound waves can travel through a variety of media, including air, water, and solids. The speed of ...
<p><strong>Step-by-Step Solution:</strong></p><p>1. <strong>Understanding Sound Waves</strong>: - Sound waves are classified as mechanical waves. This means they require a medium to travel through, unlike electromagnetic waves which can travel throug
