How big is average periscope?
It depends on the periscope type. For traditional periscopes that utilize a prism and raised mast, the entire mast is about 50' long. For newer types that utilize hi-resolution camera arrays (photonics masts) about 30', since they have no need to be housed within the primary hull.
Does a periscope work to refract light?
Periscopes work by reflecting light, not refracting it. Light enters the top of the periscope and is reflected through 90 degrees by either a plane mirror or a right angled prism (TIR) and travels down the tube where it is reflected again along the eyepiece to the eye.
