An object is placed at a distance of 30 cm in front of a convex mirror of focal length 15 cm. Write four characteristics of the image formed by the mirror.

Explanation

To solve the problem step by step, we need to determine the image distance using the mirror formula and then identify the characteristics of the image formed by the convex mirror.

### Step 1: Identify the given values
- Object distance (u) = -30 cm (the negative sign indicates that the object is in front of the mirror)
- Focal length (f) = +15 cm (the positive sign indicates that it is a convex mirror)

### Step 2: Use the mirror formula
The mirror formula is given by:
