Lithograph is a type of print, not a medium. Printing is a medium, painting is a medium, lithography is a medium, but a lithograph is a product, like A painting is a product. Lithos are usually drawn with grease pencils of some sort in a mirror image of the subject you want on a smooth stone or metal plate, then water-based inks are applied, one color to each pass of the print.

A medium is a channel through which information or communication can be transmitted. It can refer to a person who claims to communicate with the spirits of the dead, or to a substance that something is transmitted through, like air or water.
In science medium usually refers to the environment or conditions an experiment is carried out under.
For example, some chemical reactions take place in an aqueous medium, or some physical tests they make a special substance that reduces outside interference (like in CSI when they fire bullets into a tub of goo, that goo is the "medium" the experiment takes place in).
Medium is already singular. The plural is mediums.
The ray of light bends away from the normal when traveling from a less optically dense medium (medium A) to a more optically dense medium (medium B). Therefore, medium B is optically denser in this scenario.
False. Waves do not carry the medium with them as they travel through it. Instead, they transfer energy through the medium without permanently displacing the particles of the medium.
Medium is of two type One is material medium and other one is non-material Material medium are air medium, water medium etc Non-material medium is vacuum or free space If material medium is essential for the propagation of the wave then that wave is named as mechanical wave. Example: sound waves If such a material medium is not a must then the wave is said to be Electro magentic wave. Example: Light waves.
Most of the wave energy is reflected back into the denser medium when a wave moves from a dense medium to a less dense medium.
