No, light travels fastest through a vacuum (ie, in space). This applies to the entire EM spectrum.
no. if the medium is denser, the reflection of light would not do it.
it is necessary to identify the optical density of a particular medium air for example is 1.00 and the refraction in a medium can be figured out by sinøincidence ÷ sinø refraction
To produce laser light, three conditions are necessary: a gain medium to amplify the light, an energy source to excite the atoms in the gain medium, and an optical resonator to select and amplify the light through stimulated emission. These conditions allow for the emission of a coherent and collimated beam of light with a narrow wavelength range.
No not really. Sound waves are mechanical waves. They require a medium for propagation. On the other hand, Light waves are electromagnetic and do not require a medium. Hence you cannot hear in space. AND light waves reach the earth from the sun through space- which is a vacuum!!
When light enters a different medium, the amount that the light is bent as it enters the medium is determined by the medium's index of..........=refraction

Lasers typically have three main components: a gain medium (such as a crystal or gas) that amplifies light, an energy source (such as a pump source) to provide the necessary energy for the gain medium to amplify light, and optical cavity or resonator to reflect and amplify the light in a coherent manner.

no they do not have a medium.

c divided by the index of refraction of the medium = the speed of light in the medium.
