Design an experiment to show that concave mirror is a converging mirror.
Answers
Answer:
the size of the image is lesser than the size of the object, it is a convex mirror. If the size of the image is greater than the size of the object, it is a concave mirror. If the size of the image is equal to the size of the object, it is a plane mirror.Originally Answered: A concave mirror always forms a real image. ... If an object is further away than the focal length, then the image is real. On the other hand, if an object is closer to the mirror than its focal length, then the image is virtual.Focal Length - The distance between the pole P of the concave mirror and the focus F is the focal length of the concave mirror. Thus, the focal length of a concave mirror can be estimated by obtaining a 'Real image' of a distant object at its focus, as shown in the figure.
