free space is where there is no opposition force ,but in vaccum there are some force opposite to every reaction as per our since knowledge but as remove this it becomes space
A solid has little free space between particles.
A volume empty of free molecules refers to a vacuum, where there are no gas molecules present. In a perfect vacuum, all matter has been removed, leaving behind a space that is devoid of any particles. Such environments are commonly used in scientific experiments and industrial processes.
Vacuum we mean that there is nothing in the space. But perfect vacuum is not possible even in space as there are some traces of hydrogen molecules. More over space itself is having some properties such as magnetic permeability and electric permittivity. So space is considered as a medium through which light could travel. But sound cannot travel as it needs material medium. Hence sound waves are called as mechanical waves where as light waves are named as electromagnetic waves.

The speed of light in a vacuum is constant at about 3 x 10^8 meters per second. The nature of the source of the light wave does not directly influence the speed of light in a vacuum. The speed of light is determined by physical constants in the vacuum, such as the permeability and permittivity of free space.
"Free Space", the vacuum of space..
Free space is space that is available to be filled or used for some purpose. Emptiness is the state of containing nothing, but as all space contains something there is no place that is completely empty. I might add that a vacuum is not competely empty.
Conductivity of free space can be approximated to be equal to the conductivity inside of a vacuum, which is zero.
Motels contains free space between rooms and reception while inn doesn't have this.
Divergence: rate of spread of vector in free space for non closed path. and Curl: rate of spread of vector in free space for closed path.
Free space laser communication refers to the optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking. Free space refers to the vacuum, outer space or air.
A solid has little free space between particles.
The speed of an electromagnetic wave in a vacuum is a fundamental constant of nature, denoted by the symbol 'c'. The value of the speed of light in a vacuum is approximately 299,792,458 meters per second. This value is derived from the properties of free space and the relationship between electric and magnetic fields in vacuum.
Light being electromagnetic wave is able to traverse right from Sun to the Earth through vacuum existing in between the two. This confirms electromagnetic wave can traverse through free space. Now free space itself is a medium but not a material medium.
-- look up the electrostatic permittivity of free space -- look up the magnetic permeability of free space -- multiply them -- take the square root of the product -- take the reciprocal of the square root The number you have is the speed of light in a vacuum.
