Question

You observed light passing through lenses and through a set of prisms. Why does refraction occur? Include your lab observations in your answer. Respond to at least two other posts and evaluate the thoroughness and accuracy of each response.

Can you please explain this or break it down for me I need help.

Thank you

Answer 1

refraction occurs at a boundary where the speed of the wave changes. Google Snell's law
