We can burn a piece of paper by focussing the sun rays by using a particular type of lens.
Draw a ray diagram to support your answer.

Explanation

To solve the question of how we can burn a piece of paper by focusing sunlight using a lens, we will create a ray diagram that illustrates the process. Here’s a step-by-step text solution:

### Step 1: Identify the Lens Type
We need to use a **convex lens** (also known as a converging lens) because it can focus parallel rays of light to a single point.

**Hint:** Remember that a convex lens is thicker in the middle and thinner at the edges.

### Step 2: Draw the Lens
