In order for a real object to create a real, inverted enlarged image,
a) we must use a concave mirror.
b) we must use a convex mirror.
c) neither a concave nor a convex mirror can produce this image.
- A convex mirror can only produce a virtual image since all reflected rays will diverge. Therefore, b) is false.
- To create a real image with a concave mirror, the object must be outside the focal point.
- The example we just did gave a real, inverted reduced image.
- Is it possible to choose the parameters such that the image is enlarged??
The easy (but clever) answer:
- Therefore consider the OBJECT to be h’. The IMAGE will be h !!!
- Therefore it certainly IS POSSIBLE!!
