WebHow does the speed of light change with the density of a medium? Solution : A medium is denser than air, if its speed of light in the medium is less than the speed of light in air. Similarly, a medium is less dense than air, its speed of light in the medium is more than the speed of light in air. Speed of light is 1/density of medium. WebAnswer The light waves that go through the glass don't actually slow down. The effect is only apparent and applies to the speed of light 'in the material' as opposed to the speed of light 'in vacuum' where light ALWAYS travels at the speed of light c. The reason you treat the light as if it did slow down is an effect of the wave nature of light. WebWell, if you think light is a wave, it's easy to explain. Electromagnetic waves simply travel slower through glass than through air. So the wave crests are closer to each other, but the … orchestration planning
