Concave Mirror Image Formation
Different kinds of images can be created by shifting the object's position in the concave mirror. When the object is positioned, various images are created:
- At the infinity
- Beyond the centre of curvature
- At the centre of curvature
- Between the centre of curvature and the principal focus
- The principal focus
- Between the principal focus and pole
At what distance from a concave mirror of focal length 10 cm should an object 2 cm long be placed in order to get an erect image 6 cm tall?
An object 2 cm long should be placed at a distance of -6.7 cm from a concave mirror with a focal length of 10 cm in order to obtain an upright image of 6 cm tall. The formula to determine the object distance is m = hi/ho and 1/v + 1/u = 1/f.
