WebLight is observed as traveling at velocity v=c, according to the second postulate of special relativity. But according to the principles of special relativity, light is not traveling, and this is why no medium is needed: The worldline of light is lightlike, and lightlike spacetime intervals are zero (empty). WebIt’s the energy from your clap that travels all the way to your ears, not the particles themselves. It’s also important to remember that the particles are moving in the same direction as the wave is moving. If you drop a marble into a bucket of water, you will be able to see the ripples that are produced making humps and dips in the water.

Light Travels in Straight Line - Vedantu

WebWhen light traveling in one transparent medium encounters a boundary with a second transparent medium (e.g., air and glass), a portion of the light is reflected and a portion is transmitted into the second medium. As the transmitted light moves into the second medium, it changes its direction of travel; that is, it is refracted. WebThe light waves travel slower in glass than in air because the density of the glass is greater than the density of the air.
