Light travels in straight lines until it hits a prism, where it bends and spreads out into different colors. This bending, called refraction, happens when light moves from one transparent medium to another. Depending on the frequency of the wave, it could refract more or less. That's why rainbows form and why images in water can look distorted.

This refraction makes a pencil in water appear broken. Understanding this concept helps us grasp how light behaves differently in various materials.
