Answers
Many phenomenon from everyday life are associated with refraction. Here are a few:
Pickles are usually sold in circular glass jars filled with vinegar. As a result, the pickles in the jar appear bigger than they really are.
In scuba diving classes, instructors warn their students that the objects they see underwater seem 25% larger than actual size.
Always be careful when you dive into a lake. The bottom is really deeper than it appears to be.
However the rocks that you see are actually closer to you than you think.
Your glasses and contact lenses alter the path of light to compensate for defects in your vision.
To catch fish in an aquarium, stand so that you are looking straight down into the tank. Otherwise, you'll have a difficult task since the fish are not really where you think they are.
At sunset, just when the sun has almost disappeared from view, it is actually below the horizon. It appears to be higher in the sky than it really is.
Therefore, we are living in the world of refraction
