Expert Answer
To find the focal length of the concave mirror, use a similar procedure as you did with the convex lens. Arrange your mirror, meter stick, and screen. Point the mirror at distant (greater than 10 m) object and move the screen along the meter stick until you obtain a sharp image of the distant object on the screen. The distance between the mirror and the screen is the approximate focal length of the mirror. Record this in the table.
