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. For most macroscopic purposes, though, its behavior can be described by treating it as a wave ...
24. As I understand it, electromagnetic waves have two components which are the result of each other, i.e., when a moving electric charge creates a changing magnetic field at point X then a changing electric field is created at point Y and this repeating process is what creates EM waves, so therefore, it requires no medium.

The wave-particle duality of light simply means that light behaves as both waves and particles. Although this has been long accepted as fact, scientists only managed to observe both these properties of light¹simultaneously for the first time in 2015. As a wave, light is electromagnetic radiation—vibrations, or oscillations, of the electric and magn...
Waves are the transference of energy from one point to another. If we dropped a pebble into a small pond, the energy that the impact creates would transfer as a ripple, or a wave, that travels through the surface of the water, from one water particle to another, until eventually reaching the edge of the pond. This is also how sound waves work—excep...
Light propagates through transverse waves. Transverse waves refer to a way in which energy is transferred. Transverse waves oscillate at a 90-degree angle (or right angle) to the direction the energy is traveling in. An easy way to picture this is to imagine an S shape flipped onto its side. The waves would be going up and down, while the energy wo...
The simple answer to this question is no, as far as we know at this time, nothing can go faster than the speed of light¹. Albert Einstein’s special theory of relativity states that “no known object can travel faster than the speed of light in a vacuum.” Space and time don’t yet exist beyond the speed of light—if we were to travel that fast, the clo...
Light travels through space as transverse, electromagnetic waves. Its wave-particle duality means that it behaves as both particles and waves. As far as we know, nothing in the world travels as fast as light. Featured Image Credit: NASA, Unsplash
- How far does light go? how long does light go. - Jason (age 11) A: Hi Jason, Light just keeps going and going until it bumps into something.
- less than one photon? Can light intensity reduce to a level where it's energy is less than 1 photon (probably after travelling an almost infinite distance from a point source)?
- stars too far away to see? does there is any star that we can can't get it's light because of itis farness?...... sorry with having any problems in my English gramer, my English language is not good enough.
- light going out to space. If we are reflections of light, does that reflection make it out into space and keeps traveling til its asorbed.
Feb 18, 2024 · A: Light is an electromagnetic wave that does not require a material medium to propagate. This allows it to travel through the vacuum of space without encountering any resistance. Q: How fast does light travel through space? A: The speed of light in a vacuum is approximately 299,792 kilometers per second or about 186,282 miles per second. Q ...
May 20, 2016 · And how can it behave like a wave and pass through a vacuum, when all other waves require a medium to propagate? ... things move close the speed of light, including the time-space frame of a ...
