Light does not travel at the same speed in all media because there are different densities. - When light changes media, it changes direction: this is refraction. It was a super fun experiment! We got to see for ourselves how light makes the water tricks
We have learned that an opaque object is one that does not allow light to pass through it. A translucent object allows some light to pass through it. When light interacts with the object, we obtain information about its shape, colour, whether it is opaque or translucent, etc.
