Копія Concave and Convex Mirror Ray Diagram

Explore image location and size for both concave and convex mirrors. You can drag the point called object to change the location (drag horizontally) and height (drag vertically) of the object.
What phenomenon does the failure of all 3 lines to cross neatly at a single point demonstrate? When is the image right side up? When is the image real? When is the image larger than the object? What does moving the object point through the mirror correspond to physically? How does this connect to the sign conventions for mirrors?
