If it was written for scientific audiences it would use proper terms instead of factually wrong "light slows down". It's not "easier to understand" when it is wrong. Speed of light does not change.
- om2 1y agoThe speed of light in a vacuum does not change. The speed of light in a non-vacuum medium can be different than the speed of light in a vacuum, however. And light passing from one medium to another changes speed (and is refracted). See https://en.wikipedia.org/wiki/Refractive_index https://en.wikipedia.org/wiki/Refractive_index
