Müller-Breslau's principle
When we draw a line on a piece of paper, it is called a straight line. But sometimes when we look at it closely, it seems like it is bending. This happens because of something called refraction, which means the way light bends when it passes through materials like glass or water.
Müller-Breslau's principle helps us understand this bending of light. It says that the amount of bending depends on two things: the angle that the light hits the material at, and the material itself.
Think of it like throwing a ball at a wall. If you throw the ball straight at the wall, it will bounce straight back at you. But if you throw it at an angle, it will bounce off at a different angle. And if you throw it at a softer surface, like a pillow, it will bounce off at a different angle than if you threw it at a hard surface like a wall.
This is what happens with light when it hits a material at an angle. The angle and the material determine how much the light will bend, and where it will come out on the other side.
So when we look at a straight line that seems to be bending, we can use Müller-Breslau's principle to understand why. It helps us see that the angle of the light and the material it's passing through are causing the bending we see.
