Practice question

**Mirror formula** 1/f = 1/v + 1/u governs spherical mirrors, f = R/2, R radius of curvature (m), u object distance (m), v image distance (m), sign convention: distances in front of mirror negative for real is convention but magnitude used, magnification m = -v/u, concave forms real inverted when object beyond F, virtual erect within F. For a concave mirror, if the object is placed beyond the center of curvature (C), the image is formed between the focal point (F) and C. The rays converge after reflection, producing a real image that is inverted and diminished in size compared to the object. Substituting values
