A concave mirror produces a virtual, erect image when the object is ______

Options

A. between F and C
B. at F
C. beyond C
D. between pole and F

Explanation

To solve the question "A concave mirror produces a virtual, erect image when the object is ______", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Properties of Concave Mirrors**:
- Concave mirrors can produce both real and virtual images depending on the position of the object relative to the mirror.

2. **Identify Image Formation Conditions**:
- For a concave mirror:
- If the object is placed beyond the center of curvature (C), a real and inverted image is formed.
- If the object is placed at the center of curvature (C), a real and inverted image is formed at the same position.
- If the object is placed between the center of curvature (C) and the focus (F), a real and inverted image is formed.
- If the object is placed at the focus (F), the rays of light will be parallel, resulting in an image at infinity (which is also real).
- If the object is placed between the focus (F) and the pole (P), a virtual and erect image is formed.

3. **Determine the Correct Position for Virtual and Erect Image**:
- From the above conditions, we can conclude that a concave mirror produces a virtual and erect image when the object is placed between the pole (P) and the focus (F).

4. **Final Answer**:
- Therefore, the correct answer is: "A concave mirror produces a virtual, erect image when the object is **between the pole and the focus**."
