It just does not bend, its common sense
Edit: light does bend, but it is so fast, it doesn't look like it's bending. If you shoot a laser into the water, you can see that it bends as it touches the surface. Also, you can see that from the night sky. Stars' gravity can bend lights, sometimes stars appears to be bigger, or smaller than it really is.
But remember Newton's Laws. A body set in motion will continue ...
Light travels in straight paths because of its reflection
light travels in straight paths called rays
Because a straight line is the shortest path it can follow between two points. However a locally straight line may not be a globally straight line. This is how a gravitational field bends the path of light according to General Relativity.
Yes because, Light travels in a straight path called a light ray.
To support that light travels in a straight path, take a flashlight and turn it on. Then, you could point it in any way around a room, upside down, angled, tilted, etc., and where ever you shine the flashlight, the ball of light is always straight across from the flashlight.
light takes a straight path.
light travels in a straight path
Yes. But the path of light across the water/air boundary is not.
A line is a straight path that goes on forever in both directions. A ray is a straight path that goes on in one direction.
Light travels in straight paths because of its reflection
It is a straight line.
light travels in straight paths called rays
A line.
From rectilinear propagation of light.
If you mean a straight path, rather than a strait path, then it is a ray.
A ray is a straight path of points that goes on forever in only one direction. A line would go on forever in two directions.
A geodesical path
