In the absence of external forces, there's nothing to cause it to bend.

How does light travel in straight lines and in waves?

Light can be described as electromagnetic waves, which travel in straight lines because they do not bend or deviate unless they encounter an obstacle or medium that can refract or reflect them. The wave nature of light explains phenomena such as interference, diffraction, and polarization.


What is the straight line which light travels in a straight line called?

Trajectory


Is a shadow proof that light travels in a straight line?

Yes, a shadow is proof that light travels in a straight line because shadows are formed when an object blocks light that is traveling in a straight path from the source to the surface where the shadow is cast. If light did not travel in a straight line, shadows would not form as they do.


What kind of line does light travel through?

Straight line.


How can light passes through?

light passes in straight line


What kind of line does light travel?

Normally light travels in a straight line. However, it has been demonstrated that gravity can bend the path of light.


Give an experiment to prove that light travels in a straight line?

Place objects in the path of a beam of light in a dark room. If the beam is blocked by the objects, light is not traveling in a straight line. However, if the objects cast distinct shadows with sharp edges, it demonstrates that light does travel in a straight line.


When does light travel in straight line?

no it does not


Why does light travel straight?

light travels in a straight line because it can only be bend by reflective objects.


What shape does light travel at?

Light travels in a straight line, moving in a straight path known as a ray.


What is it called when a straight line that represents a light wave?

A straight line that represents a light wave is called a ray. It is used to show the direction of light propagation in geometrical optics.
