In a uniform medium, light travels in a ______.

Explanation:
Light travels in a straight line when the surrounding material is uniform, meaning its properties are the same everywhere. In that situation, light doesn’t change speed or turn as it moves, so it goes straight ahead. If light encounters a boundary between different substances, its path can bend (refraction) or bounce off (reflection), which is why it wouldn’t stay on a straight line in those cases. The straight-line path is the natural behavior in a uniform medium.
