Mirror Equation Formula
The following equation is used to calculate the radius of curvature and focal length
1/O + 1/I = 2/R = 1/f
- Where R is the radius of curvature
- f is the focal length
- O is the object distance
- I is the image distance
Mirror Equation Definition
The mirror equation describes the relationship between the radius of curvature of a mirror and the focal length of the mirror.
Mirror Equation Example
How to use the mirror equation?
- First, determine the object distance.
Calculate the distance from the object to the mirror.
- Next, determine the image distance.
Calculate the image the mirror projects the object from the mirror itself.
- Finally, calculate the focal length and radius.
Calculate the radius of curvature and focal length using the equation above.
FAQ
The mirror equation is, 1/O + 1/I = 2/R = 1/f. It’s used to calculate the radius of curvature and focal length of a curved mirror.
The focal length is the distance from the center of the mirror in which reflect light is most densely focused.
