The principal focus is in front of the concave mirror and is behind the convex mirror. Focal length: The focal length (denoted by FP in the fig.) is the distance between the pole P and the principal focus F of a curved mirror. The focal length is half the radius of curvature. Focal...
Suppose she wants an erect with a magnification of 2.00 when the mirror is 1.25 cm from a tooth. (Treat this problem as though the object and lie along a straight line.) (b) What must be the focal length and radius of curvature of this mirror? 513 views...
1. Identify the Focal Length: The focal length (f) of the convex mirror is given as 50 cm. 2. Apply the Formula: We use the formula for the radius of curvature: R=2f 3. Substitute the Value of Focal Length: Substitute the given focal length into the formula: R=2×50cm 4. ...
The image formed by concave mirror is always real except when the object is placed between pole and focus. The image formed by the convex mirror is always virtual. The radius of curvature is double of magnitude focal length.Answer and Explanation: ...
Answer true or false: The focal distance of a concave mirror is positive. Define the focal length of a convex mirror? The radius of curvature of a concave mirror is 20cm. Its focal length is what? The focal length of a concave mirror has a magnitude of 20 cm. What is its r...

Although the change in beam radius is often regarded as a the actual function of a lens, its essential function is the change in wavefront curvature, which is the actual reason for changes in beam radius during propagation after the lens. (Note that the optical energy always propagates in ...
