For finding the focal length of a concave mirror, where do we keep the object? What is the position of image formed? On which structure we get the image? What is the nature of the image formed
Best Answer
A large sized object placed at a far off (Infinity) place, seen from the window of the lab, is taken as object.
The image is formed at F point of the mirror. This image is formed on the screen.
The distance between the mirror and the screen is measured; which is equal to focal length of the mirror. The image formed is real and inverted
