Jul 7, 2021 · Light waves are similar, but while mechanical waves cause oscillations in matter, light waves consist of electric and magnetic fields oscillating perpendicular to each other. Mechanical waves need matter in order to propagate, but light waves can travel through completely empty space as well as through matter.
Unlike a sound waves, light waves do not need a medium to pass through, they can travel through a vacuum. Light from the Sun reaches Earth through the vacuum of space. A short video...
Jun 8, 2022 · Light, or electromagnetic waves, are just that, waves in the background electromagnetic fields. You could argue that they indeed have a medium, the EM field. This is similar to sound, which is pressure waves in a substance.
Apr 24, 2017 · The question of how light travels through space is one of the perennial mysteries of physics. In modern explanations, it is a wave phenomenon that doesn't need a medium through which to propagate. According to quantum theory, it also behaves as a collection of particles under certain circumstances.
Unlike sound waves, light waves can travel through a vacuum close vacuum Empty space, where there is no solid, liquid or gas present. – they do not need a substance to travel through.
Jul 29, 2023 · Water waves require water to travel in. The sound waves we hear, to give another example, are pressure disturbances that require air to travel though. But electromagnetic waves do not require water or air: the fields generate each other and so can move through a vacuum (such as outer space).
