### Correct Option: B. Real and inverted ### Detailed Explanation: When parallel rays of light strike a concave mirror, the behavior of the light rays and the characteristics of the image formed depend on the position of the object relative to the mirror's focal point and center of curvature. 1. **Understanding the Concave Mirror**: - A concave mirror is a spherical mirror that curves inward, resembling a portion of the interior of a sphere. - It has a focal point (F) where parallel rays of light converge after reflecting off the mirror. The center of curvature (C) is located at a distance equal to twice the focal length (C = 2F). 2. **Position of the Object**: - In this scenario, the object is placed beyond the center of curvature (C). This means the object is located at a distance greater than 2F from the mirror. 3. **Ray Diagram**: - To visualize the situation, we can draw a ray diagram: - Draw a concave mirror with its focal point (F) and center of curvature (C) marked. - Draw parallel rays coming from the object towards the mirror. - The first ray travels parallel to the principal axis and reflects through the focal point (F). - The second ray travels through the focal point (F) and reflects parallel to the principal axis. - The intersection of these reflected rays indicates the position of the image. 4. **Image Characteristics**: - When the object is beyond the center of curvature, the reflected rays converge to form a real image. - A real image is one that can be projected onto a screen, as the light rays actually converge at the image location. - The image formed is also inverted, meaning it is upside down compared to the object. 5. **Conclusion**: - Therefore, when parallel rays of light strike a concave mirror with the object placed beyond the center of curvature, the image formed is **real and inverted**. ### Why Other Options Are Incorrect: - **Option A: Virtual and upright**: - A virtual image is formed when the object is placed between the focal point and the mirror. In this case, the image would be upright and cannot be projected onto a screen. Since the object is beyond C, this option is incorrect. - **Option C: Real and upright**: - A real image formed by a concave mirror is always inverted when the object is placed beyond the center of curvature. Therefore, this option is incorrect because it contradicts the nature of real images. - **Option D: Virtual and inverted**: - A virtual image cannot be inverted; it is always upright. This option is incorrect because it mischaracterizes the nature of virtual images. ### Summary for Revision: - A concave mirror forms a real and inverted image when the object is placed beyond the center of curvature. - The image can be projected onto a screen, as the light rays converge at the image location. - Ray diagrams are essential for visualizing how light behaves with mirrors. - Remember the relationship: Object beyond C → Real and inverted image.
