Lines of least travel time.
Light travels in straight lines that we call rays.
rays.
light is called a ray because light travels in straight lines
Light is a visible form of energy that travels in straight lines. It can also appear invisible, such as with ultraviolet or infrared light.
Light travels as light energy. Light is a type of electromagnetic wave.
One way to demonstrate that light travels in straight lines is by observing shadows. When an object blocks light, it creates a shadow that has a well-defined edge, showing that light travels in straight paths. Another way is by using a pinhole camera, where light passes through a small hole and creates an inverted image on a screen, also indicating that light travels in straight lines.
Yes, when light travels in straight lines, it can be reflected off surfaces or refracted when passing through different mediums with varying densities. Reflection occurs when light bounces off a surface, while refraction happens when light changes direction as it travels from one medium to another.
Light travels in straight lines because it does not exhibit visible diffraction or interference in everyday scenarios. When light encounters a boundary between two mediums with different refractive indices, it refracts but still travels in a straight line within each medium. This behavior is explained by the wave theory of light.
Light rays travel in straight lines due to the principle of the shortest path, known as Fermat's principle. Light travels along the path that minimizes the time it takes to travel from one point to another. This results in light rays following straight lines in a uniform medium.
