What is the difference between virtual images of an object formed by a concave mirror and a convex mirror?
Advertisements
Solution 1
The virtual image of an object formed by a concave mirror is always magnified but the image formed by a convex mirror is always a diminished one.
Solution 2
| Basis | Concave Mirror | Convex Mirror |
| Size of Image | Magnified (larger than the object). | Diminished (smaller than the object). |
| Object Position | Only when the object is between the Pole (P) and the Focus (F). | For all positions of the object in front of the mirror. |
| Field of View | Narrow; used for seeing detail. | Wide; used for seeing a large area. |
| Common Use | Shaving mirrors or dentist mirrors. | Rear-view mirrors in vehicles. |
