Trajectory
Yes because, Light travels in a straight path called a light ray.
I have the straight answer from the Internet and my science teacher that light travels in the motion of waves.
It does not, it travels as a wave
A geodesical path
All light travels as a wave
Light the electromagnetic wave.
In a straight line. At the speed of light.
Actually, it has been proved that light is bent by gravity, so it is impossible to prove that light travels in a straight line.
light travels in a straight line because it can only be bend by reflective objects.
Electricity.
A laser
Light behaves simultaneously as a wave and as a particle.
