Image in a concave mirror
Move an object in front of a concave mirror and locate its image.
What to notice
Beyond the centre of curvature the image is small and inverted; inside the focus it is virtual.
Key relation
1/f = 1/v + 1/u
Try this
Move the object inside the focal length.
What you can change
- Object distance: 5 to 60 cm
- Focal length: 8 to 30 cm
