A small candle `2.5 cm` in size is placed `27 cm` in front of a conacave mirror of radius of curvature `36 cm`. At what distance from the mirror should a screen be placed in order to receive a sharp image ? Describe the nature and size of the image. If the candle is moved closer to the mirror, how would the screen have to be moved ?

To solve the problem step by step, we will use the mirror formula and the magnification formula. Here’s the detailed solution:
### Step 1: Identify the given values
- Height of the candle (h1) = 2.5 cm
- Object distance (u) = -27 cm (negative because the object is in front of the mirror)
- Radius of curvature (R) = -36 cm (negative for concave mirror)
### Step 2: Calculate the focal length (f)
