You observed light passing through lenses and through a set of prisms. why does refraction occur? include your lab observations in your answer.

I don't have your lab observations, but I can give you the reason why refraction occurs.

Refraction refers to the bending of light at the interface as it passes through mediums of different densities.

Refraction occurs because light travels at different speeds in mediums with different densities.

Hope this helps!

Iwould say overuse ( but not 100% sure ) in the u.s. we tend to overuse water by leaving it running, throwing it away, taking long showers, etc.
