Explain why it's accepted that light is rectilinear. It doesn't really seem like it.

Light is considered to be rectilinear because it travels in a straight line, following the laws of geometric optics. This means that light will continue in a straight path until it is either absorbed or reflected by an object or surface.
The concept of rectilinear light was first accepted through the experiments and observations of ancient Greek philosophers such as Euclid and Aristotle. They observed that light travels in a straight line and proposed geometric theories to explain this phenomenon.
One of the main pieces of evidence supporting the idea of rectilinear light is the observation of shadows. When an object blocks a source of light, a shadow is created in the shape of the object, indicating that light travels in a straight path. Additionally, experiments with lenses and mirrors have also confirmed the rectilinear nature of light.
While light is generally considered to be rectilinear, there are some situations where it does not behave in a straight path. This includes phenomena such as diffraction, where light waves bend around obstacles, and refraction, where light changes direction as it passes through different mediums.
The concept of rectilinear light plays a crucial role in many everyday technologies, such as cameras, telescopes, and microscopes. It also helps us understand the formation of images, the behavior of light in different environments, and the principles of geometric optics, which have practical applications in fields such as engineering and architecture.
