Ray Optics: Spherical Mirrors
An interactive journey through the fascinating world of reflection!
Focal Length
Discover how parallel rays converge or diverge
Mirror Equation
Explore the relationship between object and image

Concave vs Convex Mirrors: Side-by-Side Comparison
Property
Concave Mirror
Convex Mirror
Shape
Curved inward (like a spoon)
Curved outward (like a ball)
Focal Point
In front of the mirror (real)
Behind the mirror (virtual)
Focal Length
Positive (+)
Negative (-)
Image Types
Can form both real and virtual images depending on object position
Always forms virtual images regardless of object position
Image Orientation
Can be inverted or upright depending on object position
Always upright
Image Size
Can be enlarged, diminished, or same size depending on object position
Always diminished (smaller than object)
Object at Infinity
Forms real, inverted, diminished image at focal point
Forms virtual, upright, diminished image at focal point
Object at Focal Point
No image formed (rays become parallel)
Forms virtual, upright, diminished image
Field of View
Narrower field of view
Wider field of view
