1. Light from the objects outside the window strikes the surface of the glass.
2. As light enters the glass, it bends, or refracts, due to a change in its speed. The speed of light is slightly slower in glass compared to air. This change in direction is governed by Snell's law of refraction.
3. The refracted light rays then pass through the glass, which is transparent. Transparent materials allow light to pass through them easily with minimal absorption or scattering.
4. As the light exits the glass at its opposite surface, it undergoes refraction again, bending away from the normal (perpendicular) to the surface.
5. The refracted light rays continue their path towards your eyes, carrying the visual information about the objects outside the window.
6. Your eyes receive the refracted light rays, focusing them on the retina. This process forms an image of the objects outside on the retina, similar to how a camera lens focuses light onto a film or sensor.
7. The brain interprets the information received from the retina, allowing you to perceive and recognize the objects outside the window.
Through this process of refraction and transmission of light, you are able to see objects outside a window as if there were no barrier between you and them.
