What is the relation between wave length and radius of curvature

1.	What is the relation between wave length and radius of curvature
Answer» EXPLANATION: The distance from the pole to the center of CURVATURE is called (no SURPRISE, I hope) the radius of curvature (r). The distance from the pole to the focal point is called the focal LENGTH (f). The focal length of a SPHERICAL mirror is then approximately half its radius of curvature. The distance from the pole to the center of curvature is called (no surprise, I hope) the radius of curvature (r). The distance from the pole to the focal point is called the focal length (f). The focal length of a spherical mirror is then approximately half its radius of curvature.f ≈ r/2 It is important to note up front that this is an approximately true relationship
