Refraction occurs due to the change in speed of light as it passes from one medium to another. Here are the steps explaining why refraction occurs:

1. Light is a form of energy that travels in waves. The speed of light is fastest in a vacuum, such as space.

2. When light travels from one medium to another (for example, from air into water), it changes speed, slowing down as it enters a denser medium (like water) and speeding up as it enters a less dense medium (like air).

3. This change in speed causes the light wave to change direction, a phenomenon known as refraction.

4. The degree to which the light bends, or refracts, depends on the angle at which the light hits the new medium and the refractive indices of the two media. The refractive index of a medium is a measure of how much the speed of light is reduced inside the medium.

5. If the light enters the new medium at an angle, one side of the wave will slow down before the other, causing the light to change direction. If the light enters the new medium straight on, it will slow down, but it won't change direction.

6. This bending of light is what causes objects to look distorted when we look at them through water or a glass block. It's also what makes lenses work, whether in glasses, cameras, or our own eyes.
