Single Lens Reflex cameras have an optical viewfinder. You are looking right through the lens and the mirror / "pentaprism" combination directs the light up to the viewfinder you look through to compose the photo.

In an electronic viewfinder, the mirror and pentaprism are eliminated and the same image displayed on the sensor is projected into the viewfinder. This makes mirrorless cameras more accurate than compact cameras while also cutting down on bulkiness.
