Refraction and the Property of Rectilinear Propagation of Light
In refraction, light changes its path when it moves from one medium to another due to the change in the speed of light. This phenomenon might seem to contradict the property of rectilinear propagation of light, which states that light travels in a straight line in a uniform medium. However, refraction does not violate this property; it simply demonstrates how light behaves when it encounters a change in medium.

Explanation
- Rectilinear Propagation of Light: Light travels in a straight line in a uniform medium because it does not bend or deviate from its path unless it encounters a boundary between two different mediums.
- Refraction: When light enters a medium with a different optical density, such as air to water, its speed changes, causing it to bend or change direction. This bending of light is known as refraction.
- Explanation of Refraction: Refraction occurs because the speed of light is different in different mediums. When light enters a denser medium, it slows down, causing it to bend towards the normal. Conversely, when light enters a less dense medium, it speeds up, causing it to bend away from the normal.
- Conclusion: Refraction does not violate the property of rectilinear propagation of light; instead, it demonstrates how light behaves when it encounters a change in medium. The phenomenon of refraction is a natural occurrence that helps us understand how light interacts with different materials.
In conclusion, while refraction may seem to contradict the property of rectilinear propagation of light, it is simply a demonstration of how light behaves in different mediums. It is important to understand the principles of refraction to comprehend the behavior of light in various situations.
