State whether the following statements are true or false :
The image of the flame of a lighted candle formed by a concave lens can be obtained on a screen.

Options

A. True
B. False
C. None of the above
D. Options insufficient

Answer

To determine whether the statement "The image of the flame of a lighted candle formed by a concave lens can be obtained on a screen" is true or false, we can analyze the properties of concave lenses.

### Step-by-Step Solution:

1. **Understanding the Lens Types**:
- There are two main types of lenses: concave and convex.
- A concave lens is thinner in the center than at the edges and diverges light rays that pass through it.

2. **Image Formation by Concave Lens**:
- When an object (like the flame of a candle) is placed in front of a concave lens, the lens diverges the light rays coming from the object.
- The image formed by a concave lens is always virtual, upright, and reduced in size.

3. **Characteristics of Virtual Images**:
- A virtual image cannot be projected onto a screen. This is because virtual images are formed where the light rays appear to diverge from a point, but do not actually converge at that point.
- Since the image is not formed by actual light rays converging, it cannot be captured on a screen.

4. **Conclusion**:
- Since the image of the flame of a lighted candle formed by a concave lens is virtual and cannot be projected onto a screen, the statement is **FALSE**.

### Final Answer:
The statement "The image of the flame of a lighted candle formed by a concave lens can be obtained on a screen" is **FALSE**.
