Question

A scientist crafted the model to illustrate the behavior of a light ray.

\begin{tikzpicture}
\draw (0,0) -- (4,0) -- (4,2) -- (0,2) -- cycle;
\draw (0,1) -- (4,1);
\draw (1,2) -- (3,0.5) -- (3,0);
\node at (2,1.7) {Light ray};
\node at (3.5,1.5) {Air};
\node at (1.5,0.3) {Water};
\end{tikzpicture}

For what reason might a scientist create this model depicting the behavior of a light ray?
(1 point)
To clarify that light follows a curved trajectory until it transitions from one material to another.
To clarify that light follows a curved trajectory even when transitioning from one material to another.
To explain that light travels in a straight line even when transitioning from one material to another.
To explain that light travels in a straight line until it transitions from one material to another.

Answer 1

The most accurate reason a scientist might create this model depicting the behavior of a light ray is:

**To explain that light travels in a straight line until it transitions from one material to another.**

This is because the model clearly illustrates the light ray moving in a straight path in the air and then bending upon entering the water, which represents the refraction of light at the boundary of two different materials.
