I chose a video called “Just Add Water,” basically there is a clear cup filled with water and behind it lies a white piece of paper with a drawing of some sort on it, let’s use one of the examples in the video, there was a word that spelled “now” and when the water was poured into the cup it reversed the word and it portrayed the word “won.”
This is an example of refraction – the bending of light. The image isn’t actually reversed but as the water is being poured into the cup, it makes it look like it is reversed, thanks to refraction. Refraction occurs when the wave changes direction when it passes from one medium to another and as the water entered the cup, it bended and switched the direction of the image..
