Make labelled ray diagrams to illustrate the formation of:
a real image by a converging mirror.
उत्तर
A real image is formed by a converging mirror when an object is placed anywhere between the focus and infinity, including the focus and infinity:
Here, P: pole, F: focus, C: centre of curvature, AB: object and A'B': image.
