Mirror Equation & Formula
Mirror Equation: 1/f = 1/u + 1/v
Magnification: m = -v/u
Where: f = focal length, u = object distance, v = image distance, m = magnification
Mirror Types
- Concave Mirror: Converging mirror, forms real or virtual images depending on object position.
- Convex Mirror: Diverging mirror, always forms virtual, erect, diminished images.
FAQs
Q: What is focal length?
A: Focal length is the distance from the mirror's center to its focal point, where parallel rays converge (for concave) or appear to diverge from (for convex).
A: Focal length is the distance from the mirror's center to its focal point, where parallel rays converge (for concave) or appear to diverge from (for convex).
Q: What's the difference between real and virtual images?
A: Real images can be projected on a screen (positive image distance), while virtual images cannot (negative image distance).
A: Real images can be projected on a screen (positive image distance), while virtual images cannot (negative image distance).
Q: How is magnification calculated?
A: Magnification is the ratio of image height to object height, calculated as m = -v/u. Negative values indicate inverted images.

Q: When do mirrors form inverted images?
A: Concave mirrors form inverted (real) images when the object is beyond the focal point.
