Some telephoto cameras use a mirror rather than a lens. What radius of curvature mirror is needed to replace a 800 mm focal length telephoto lens?

To determine

The required radius of curvature for a mirror to replace a 800mm focal length telephoto lens.

Explanation

Given info:

Focal length of telephoto lens is 800mm.

Formula used:

Relation between focal length and radius of curvature is,

f=R2

Here,

• f is the focal length of the telephoto lens.
• R is the radius of curvature of the mirror.

Calculation:

Rearrange the above expression.

R=2f

Substitute 800mm for f in above expression
