Types of Media

            There are three different types of media, transparent, translucent, and opaque.  A transparent medium will allow Light to pass through, and will not distort the image that passes through.  An example of a transparent medium is a normal window pane.  You can see clearly through your window to the outdoors, and nothing is distorted.  A translucent medium allows Light to pass but the image won’t be clear.  Frosted glass is translucent, because you can see a faint image through it, but not a clearly defined one.  An opaque medium blocks Light completely, so you can’t see anything through it.
