You can measure the radius of curvature (R) of the mirror by measuring the distance between convex mirror and the screen placed behind the mirror. You can calculate the focal length of the mirror using the equation f = R/2.

What is the formula of focal length of concave lens?
Using the values of u and v, the focal length of the concave lens is calculated using the formula, f= uv/u-v.
What is the formula of focal length of convex lens?
So, the final answer is f=u×vu−v. Note: When the subject is in focus, the focal length of the lens is the distance between the lens and the image sensor, normally expressed in millimetres (e.g., 28 mm, 50 mm, or 100 mm).
What is the formula of convex mirror?
1/f= 1/u + 1/v. This equation is referred to as the mirror formula. The formula holds for both concave and convex mirrors.
How do you find the focal length of a concave and convex mirror?
To Determine Focal Length of a Given Concave Mirror
The screen should be placed in front of the reflecting surface of the mirror. To obtain a clear, sharp image the screen should be adjusted. Using a metre scale the distance between the concave mirror and screen can be determined.
What is focal length in mirror formula?
The focal length of a spherical mirror is given by f=R2, where R is the radius of curvature of the mirror.
How do you determine the focal length of a convex mirror?
The focal length of the mirror is calculated as, f = R/2, where f is the focal length mirror and R is the radius of curvature.
