Final answer:
The imaginary line that extends from a driver's eyes to a point of focus is a ray of light.
Step-by-step explanation:
The imaginary line that extends from a driver's eyes to a point of focus is a Ray of light.
In optics, a ray is a straight line that originates from a point and travels in a certain direction. In this case, the ray represents the path that light takes from the driver's eyes to the point they are focusing on.
Understanding how rays of light behave is important for studying the formation of images and the properties of lenses and mirrors.
