Materials that allow light to pass through them are called transparent materials.
An object that allows light to pass through it is called a transparent object.
Water is transparent because visible light can pass through it without being absorbed or scattered. This is due to the molecular structure of water, which allows light to travel through with minimal interference, enabling us to see objects on the other side of the water.
No, light doesn't need a physical medium, like air, to travel. As a matter of fact, light travels the fastest it possibly can, 2.98 * 10^8 meters per second, in a vacuum, like space. If light couldn't travel without a medium, then Earth wouldn't receive any light from the Sun.
An object that does not allow light to pass through it is called opaque. Opaque objects absorb or reflect light, preventing it from transmitting through them.
The passage of light through an object is called transmission. This process occurs when light passes through a material without being absorbed or reflected.
An object that allows light to pass through it is called a transparent object.
A telephone call travels via two posible methods or both. It can travel over an electrical current via copper wire. It more commonly travels via light through fiber optic cabling.

An object through which light cannot pass is known as opaque.
Electricity, as used by us in such things as our computers and TVs etc, requires a conductor. It is the movement of electrons along that conductor which most people call electricity. This cannot travel through space. However electricity is also a part of and related to the electromagnetic spectrum which can travel through space.
Normally, the answer to that kind of question would depend on what you call "low".In the case of light, however, probably nobody would call it a 'low' speed, becauseit's physically impossible for anything in creation to travel faster than light in a vacuum. It is possible for things to travel faster than light does in other media, but it's not exactly common, and it's still very much on the "fast" end of the scale.
