How can light (or electromagnetic radiation) travel through a vacuum when there is nothing there to act as a medium, and do so forever in all directions? For example the light coming from a star millions of light years away. Light is observed as traveling at velocity v=c, according to the second postulate of special relativity. But according to ...
- 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 · Q: Why can light travel through space while other forms of energy cannot? 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 ...
Unlike sound, light can travel through a vacuum — it doesn't need a medium.It can travel through transparent materials such as glass, water, and air. (A material light can't travel through is said to be opaque.) In a vacuum, light travels with speed 3.00 x 10 8 m/sec.This speed is given the symbol c. In a transparent medium, light slows down ...
Apr 6, 2015 · This allows light to maintain its speed and continue propagating without losing energy. This is why we are able to see stars and other objects in the universe that are millions of light-years away. 5. Can other forms of energy travel through a vacuum like light does? Yes, other forms of energy, such as radio waves and X-rays, can also travel ...
May 19, 2016 · So the question re: how can light travel through a vacuum if it’s waves is a nonsensical question. There are no collapsing wave functions in light. There’s only probabilities of position that ...
Basically, traveling at incredible speeds (299 792 458 m/s) and at different wavelengths, depending on its energy. It also behaves as both a wave and a particle, able to propagate through mediums ...
