Light the electromagnetic wave.
Light
It does not, it travels as a wave
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.
All light travels as a wave
The acceleration of an object that travels in a constant straight line velocity is zero.
straight line method
A straight line is one which travels in exactly one direction, never bending or curving.
Actually, it has been proved that light is bent by gravity, so it is impossible to prove that light travels in a straight line.
Electricity.
In a straight line. At the speed of light.
