Why light and heavier object when fall through vacuum more side by side?

This is because the weight of an object does not affect the acceleration of that object due to gravity. At Earth's surface, the acceleration due to gravity is roughly 9.8m/s2, regardless of the mass of the object.
What does differ with the mass of the object is the force of gravity. Force is equal to mass multiplied by acceleration. So a one kilogram object will fall with a force of roughly 9.8 meters squared per second squared, or 9.8 Newtons (N). A two kilogram object would fall with a force of about 19.6N (2kg * 9.8m/s2). This is why when -NOT- in a vacuum, items of different mass can fall at different rates. The additional force of the more massive object will better counter the force of friction with the air, allowing it to fall faster even though it's acceleration is the same.

How does the speed of light in glass compare to the speed of light in a vacuum?
It will depend on the type of glass, and something called its refractive index. All materials have a refractive index which will effect the speed of the light through it. The speed of light through a vacuum is 3.0x10^8 m/s, and a material such as glass will be lower than this.
What is the speed of light as it travels through a vacuum?
299,792,458 meters (186,242 miles) per second.
Why is the speed of light a fact?
A "fact" is basically anything you can state, especially if such a statement is true. Since you can say "light has a speed", and since that is true, it follows that it's a fact. Light through a "vacuum" is the meaning of "the speed of light." Light through glass is slower.
Does a beam of light have a constant speed?
Light travels at a constant speed of 299,792,458 meters per second in a vacuum. However, as light travels through different mediums, it slows down depending on the medium. The crazy thing about light though, is that if it leaves a medium and starts travelling back through a vacuum, it once again goes 299,792,458 meters per second.
Why is the speed of light limited in a vacuum?
The speed of light is not limited in a vacuum - the speed of light is fastest in a vacuum. But that is what Einstein called the "Cosmic Speed Limit" - nothing can move faster than the speed of light in a vacuum, or even quite asfast.
Why doesn't light travel through a vacuum?
Light does travel through a vacuum.
Is vacuum a medium of light?
Light can travel through vacuum, but it is not a medium.
What evidence do we have that light travel through a vacuum?
You create a vacuum in a lab, and then shine a light through it, and there is experimental proof that light travels through a vacuum. Alternatively, take the fact that light travels through space - if light could not travel through a vacuum, no light from the stars, the moon or the sun would ever reach our planet.
What object does light travel through more slowly a vacuum water or glass?
Light travels very slowly in glass compared to water and vacuum
Does light travel at its slowest speed when passing through a vacuum?
No, light is at its fastest in a vacuum.
What happens when light passes through vacuum?
it travels at c (speed of light in a vacuum)
Can gases travel through a vacuum?
No. Only light waves can travel through a vacuum.
What does light travel faster through?
Light travels fastest through vacuum.
What object falls faster a heavy object or a light object in a vacuum?
They both fall at the same rate. This is because they are both only acted upon by one force in the vacuum- gravitational acceleration. The mass, size or shape of the object do not influence the object's motion in a vacuum.
When is the speed of light the fastest?
When the light is traveling through vacuum.
Does light pass through a vacuum?
Light acts as a particle.
What is 4 ways light waves can travel?
Light waves can travel can travel in different ways depending on the object. It can travel through a vacuum which is a complete airless place, mirror, but sound has to travel through a solid or gas.
