Question

For finding the focal length of a concave mirror where do we kept the object? What is the position of image formed? On which structure we get image? What is the nature of the image formed?

Answer 1

•By keeping the object at infinity, we can find the f pichis of the mirror since the object is at infinity the image will form at focus of the mirror. Then we can measure the length between pole and focus, and that will give the focal length of mirror.

•We get image on any opaque surface.

•The image formed is Real and Inverted.
