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 ...
May 13, 2003 · 2. How does light travel through a vacuum? Light travels through a vacuum in the form of electromagnetic waves. These waves do not require a medium to propagate, unlike sound waves, which need a medium such as air or water to travel. Therefore, in a vacuum, light can travel at its maximum speed of 299,792,458 meters per second. 3. Why can't ...
Of course yes. Light from sun reaches earth through the vacuum present in the space. Light does not require any medium to travel. However, Light can also travel in medium like air, water and solids. Example,we can see things inside water and glass which is a liquid and solid, which is due to travel of light.
- 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.
Below are some key safety tips for you, your pets and your home. There are three main ways lightning enters structures: a direct strike, through wires or pipes that extend outside the structure or through the ground. Once in a structure, lightning can travel through the electrical, phone, plumbing, and radio/television reception systems.
Jan 27, 2023 · Since light travels like a wave, it can travel through a vacuum without interacting with anything. However, when light does go through something, that object can absorb some of it. Light travels through these objects, like glass and water, leaving heat behind. Think of a flashlight. When you turn it on and face it toward a pool, the light can ...

Jan 10, 2023 · A vacuum is defined as an environment devoid of matter, and it is believed that light can travel through this type of environment without the need for a medium. In this article, we will explore the physics of light transmission in a vacuum, examining how light can travel without a medium and what role reflection plays in light transmission.
