WebUnlike sound waves, light waves can travel through a vacuum (empty space). They do not need a substance to travel through, but they can travel through transparent and translucent substances. WebWaves that need a medium in order to travel; sound, earthquakes and water waves are examples of this type of wave. Electromagnetic Waves. These waves do not need a …

Sound waves can only travel through medium such as air ...

WebWhy do sound waves need a medium for their propagation? Sound needs a material medium for their propagation like solid, liquid or gas to travel because the molecules of … WebElectromagnetic waves travel without a medium.

Lesson: Waves without a Medium - SERP Institute

WebLongitudinal waves come under the category of mechanical waves, which undergo propagation through some vibration of particles of atoms present in the medium. If there is a medium’s absence, it will be impossible for the propagation purpose to indicate that longitudinal waves need a medium to travel. WebMay 21, 2014 · Most notably: A mechanical wave requires an initial energy input. Once this initial energy is added, the wave travels through the medium until all its energy is transferred. In contrast, electromagnetic waves require no medium, but can still travel through one. Since a vacuum is defined as lacking a medium, then sound and … WebSolution. Sound waves need a medium to travel, that may be solid, liquid, or gas. When the source of sound or object vibrates, the vibrations apply force on the surrounding particles. The particles near the point of generation get displaced from their equilibrium position. This set of particles applies force on the adjacent particles and comes ... higma twitter
