QUESTION: Would people's legs look different to them in they looked down at their legs when swimming in the pool versus standing on a sidewalk?

A student conducting an investigation with light had the question shown. Based on this question, which of the following could be the student's hypothesis?

• I think the water magnifies their legs making them look bigger.

• If people stand in the water, then their legs will look more bent than when they stand on the sidewalk.

• Do my legs look bent while standing in the water?

• I know that refraction is the bending of waves.
