WebJan 13, 2024 · I read that the medium (of glass in this case) slows down light due to weak interaction. An airplane slowing down would lose altitude like the light changing course in the top half of the lens. I just don't understand how the direction of the light rays gets changed in an upward direction for the bottom half of the lens. WebPhysicists point out that the actual speed of light as measured by Roemer and his followers has not significantly changed, but rather point to a series of refinements in scientific instrumentation associated with increases in …
All About the Speed of Light and What It Measures - ThoughtCo
WebThe short answer is that it depends on who is doing the measuring: the speed of light is only guaranteed to have a value of 299,792,458 m/s in a vacuum when measured by someone situated right next to it. But let's approach the question by considering its various meanings. Does the speed of light change in air or water? Yes. WebThe speed of light depends on the medium like all the waves through which it is travelling. When light moves from one medium into another (for example, from air to glass), the speed of light changes. pride month progressive fla
