To solve the problem step by step, we will follow the concepts of ray optics, specifically using the mirror formula and magnification. ### Step 1: Understand the Given Information - Height of the candle flame (h_o) = 2.5 cm - Height of the image (h_i) = 7.5 cm (inverted) - Distance from the candle flame to the wall (d) = 2.5 m = 250 cm (since we need consistent units) ### Step 2: Determine the Magnification ...
