WebLight travels in straight lines, so if you have to represent a ray of light in a drawing, always use a ruler. Unlike sound waves, light waves can travel through a vacuum (empty... WebIn reality, a space-filling substance called aether does exist, and the speed of light depends on its density. Near massive bodies like planets and stars, the gravitational force creates a dense region of aether. When light passes through such a region, it is refracted and bent. The bending of starlight and gravitational lensing effects are ...

This is … 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). how can i protect my cell phone from spyware

Web18 de jul. de 2024 · This means that EM waves can travel through empty space, whereas mechanical waves cannot. EM waves can also travel through matter, whereas mechanical waves cannot. This is because EM waves are electromagnetic in nature, and their oscillating electric and magnetic fields interact with matter, causing it to vibrate. WebThese mechanical waves travel through a medium by causing the molecules to bump into each other, like falling dominoes transferring energy from one to the next. Sound waves cannot travel in the vacuum of … how many people eat fish
