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.
The cost of a periscope can vary depending on the size, quality, and brand. On average, a simple periscope for recreational use can range from $20 to $100. More specialized or military-grade periscopes can cost several thousand dollars.
