True or False: Sound waves travel in a straight line. False. Reason: Sound waves can bend around obstacles and can be reflected off surfaces. They follow a path that depends on the medium through which they are
Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that theycannot travel through empty space, where there are no atoms or molecules to vibrate. Can longitudinal waves be polarized?
The waves travel through these materials a bit differently than they do through air because of differences in composition and density, but the principle is the same. 声学波在介质中传播,是通过其中的原子或分子依次相互碰撞实现的。对我的音乐来说,传播介质是空气;但你也可以在水下听见声音——或者将...
Sound waves can travel only through matter. Since there’s almost no matter in interstellar space, sound can’t travel through it. The distance between particles is so great that they would never collide with each other. Even if you could get a front seat for the explosion of the Death St...
Sound pressure can also be generated through changes in force density. For instance, external electric and magnetic fields produce forces on ionized gas or plasma and are characterized as the acoustical sources of plasma waves. This article is, however, only concerned with the sound generation by ...
Long, skinny objects can also be levitated. The new system can lift heavy objects, and also provides enough control so that liquids can be mixed together without splitting into many tiny droplets, Foresti said. Everything can be controlled automatically. The system blasts sounds waves at what ...
Answer true or false: Electromagnetic waves can travel through vacuum. Why can't anything travel faster than the speed of light? How does a satellite transfer signal when it is vacuum in space? How can a rocket change direction when it is far out in space and is essentially in a vacuum?
To determine through which of the four boxes sound would not be able to travel, we need to analyze the properties of each medium present in the boxes.1. Identify the Boxes: We have four boxes: - Box A: Filled with air - B
Sound travels in mechanical waves. A mechanical wave is a disturbance that moves and transports energy from one place to another through a medium. In sound, the disturbance is a vibrating object. ... This means that sound can travel through gases, liquids and solids. ...
Sound waves can be reflected, refracted (or bent), and absorbed as light waves can be. The reflection of sound waves can result in an echo—an important factor in the acoustics of theaters and auditoriums. A sound wave can be reinforced with waves from a body having the same frequency of...
