No. It is proven that masses cause slight deviation in the path of light. The larger the mass, the more obvious the deviation.
In general, yes. In conditions on this planet, yes. It can bend over vast distances in the universe.
I have the straight answer from the Internet and my science teacher that light travels in the motion of waves.
Yes there is. Your shadow is the simplest evidence that light travels in straight line. A solar eclipse is also evidence that light travels in straight lines, as is the fact that you cannot see around corners unless you use a mirror.
Light always travels in a straight line. It's direction can be changed, by reflection or refraction, but it does not bend.
no it does not
As particles photons travel in a straight line unless they are diverted by reflection, refraction, or a magnetic or gravitational field. Note that when it comes to gravity it can also be represented that the light continues in a straight line - but the space it travels through is curved so its path appears curved to the outside observer.
no it does not
Straight line.
yes
idek
true
Light is a particle that acts like a wave and therefore does not travel in a straight line. light has nothing to do with gravity, the fourth dimension or the 'fabric' of space time.
light travels in a straight line because it can only be bend by reflective objects.
Yes because, Light travels in a straight path called a light ray.
There are more things for the light waves to bounce off of in water, so light can not travel in a straight line or as far.
travels through a uniform medium
Because light rays travel in straight line just like a ruler/scale. We can represent it with anything which is straight like a ruler...
Normal. It takes a lot of mass to bend light.
