- 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.

Jul 26, 2011 · I think I understand the basics that, light as it travels through a vacuum oscillates between a magnetic field and a electric field at 90 degrees to each other. How does this all, get a photon from point A to point B in a vacuum if there is no "ether" with which a photon can travel within?

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.
Mar 6, 2018 · Yes, light travels in a straight line in a vacuum. This is because there are no particles to scatter or reflect the light, causing it to travel in a specific direction. Does light always travel at the same speed in a vacuum?
Apr 16, 2005 · Yes, light travels at a constant speed of approximately 299,792,458 meters per second in a vacuum, also known as the speed of light. This is due to the fact that light is an electromagnetic wave, which does not require a medium to propagate.
In contrast, light waves can travel through a vacuum, and do not require a medium. In empty space, the wave does not dissipate (grow smaller) no matter how far it travels, because the wave is not interacting with anything else.
Mar 15, 2024 · Light travels through the vacuum of space at 186,828 miles per second as transverse waves, outside of any material or medium, because photons—the particles that make up light—also behave as waves. This is referred to as the wave-particle duality of light.
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...
