Light slows down in glass, water, or any other transparent medium. But why? Why does light slow down, and how can it speed up again when it leaves the medium? Wrong answer 1: The first completely wrong answer to why does light slow down in a medium is the idea that light scatters ...
In QED, the quantum mechanical theory of light, there would be an alternative explanation for the speed of light in glass. And, QFT (quantum field theory) would give the most fundamental explanation, involving the interaction of several quantum fields. This would be much more complicated than ...
Light does not experience time in the same way that we do. According to the theory of relativity, time appears to slow down for objects traveling at high speeds. Since light travels at the speed of light, time does not pass for photons, and they do not experience aging or...

Essentially light travels at a slower speed in glass than it does in air. This slow down forces the light to change directions slightly in the glass prism. The amount of the slowdown and change in direction depends on color. In this manner, when the white light travels into the glass, al...
Why does current slow down in a series than when in a parallel? Does current get used up in a light bulb? Do charges get used up? Do electrons get used up? Explain. The "efficiency" of a light bulb is the ratio of the ___. A light bulb is rated 100...
Explanations of why nocturnal insects fly erratically around fires and lamps have included theories of “lunar navigation” and “escape to the light”. However, without three-dimensional flight data to test them rigorously, the cause for this odd behavi
why does light seem to bend when crossing from air to water A.light is absorbed when entering the water.B.transparent substances slow down the light.C.light changes its way when entering the water.D.the water reflects light when light travels across
To constantly monitor and collect data, your FireStick OS must keep certain processes running in the background. This could slow down your FireStick and eventually cause buffering problems. Here is how you can turn off data monitoring and data collection: 1. Open FireStick Settings from the ho...
