you say light travels in a straight line
Light travels in a straight line.
All light travels as a wave
Light the electromagnetic wave.
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 in vacuum/air.
light travels in a straight line because it can only be bend by reflective objects.
That glass is transparent
a light ray or a laser == ==
Sort of. Technically light travels in what's called a geodesic curve, which is the straightest possible line given the local curvature of space. In empty space, that's a straight line. Near a massive object, it's not a straight line.
the light travels in a straight line becauise it is going straight on to you object what you are looking at.
Light behaves simultaneously as a wave and as a particle.
travels through a uniform medium
light travels in a straight line
Light travels in a straight line. The path of light can be bent by very massive objects because they actually bend space.
In a vacuum light always travels at 300,000,000 metre per second, and it always travels in a straight line.
Light will travel in a straight line when there is nothing to refract, reflect, or diffuse it from it's course.
If light did not travel in a straight line then the light would just bend around the body that is suppose to be making a shadow and no shadow would be observed. as there is a shadow cast by that body this proves that light does not bend and in fact travels in a straight line.
it may be that when it travels it is not changing its medium but when changed the process is called refraction
light travels in a straight line(rectilinear propagation of light)
