Why do you see the child more clearer than you see the vehicle?

• There is more light entering my eye from the child than the vehicle so my brain processes that signal.

• There is more light entering my eye from the vehicle than the child.

• I was looking directly at the child and not the car.

Based on the model, what type of material is this most likely to be?

• Glass

• One Way Mirror
