Answer:

Place the screen in front of the reflecting surface of the mirror. Move the screen back and forth until a clear, sharp image of the distant object is obtained on the screen. Measure the distance between the concave mirror and the screen with a metre scale. This distance is the focal length of the given concave mirror
