The correct Answer is:
To solve the question, we need to analyze the assertion (A) and the reason (R) provided. ### Step 1: Analyze the Assertion (A) The assertion states that "Plane and convex mirrors can produce real images of objects." - **Plane Mirrors**: A plane mirror always produces virtual images. The image formed by a plane mirror is located behind the mirror and is upright. Therefore, it does not produce real images. - **Convex Mirrors**: A convex mirror also does not produce real images. It diverges light rays, and the images formed are always virtual, upright, and smaller than the object. **Conclusion for Assertion (A)**: This statement is false because neither plane mirrors nor convex mirrors can produce real images. ### Step 2: Analyze the Reason (R) The reason states that "A plane or convex mirror can produce a real image if the object is virtual." - A virtual object is an image formed by a real object when it is placed in front of another mirror. For instance, if we have a plane mirror and an object is placed in front of it, the image formed is virtual. If we then place a convex mirror in such a way that it reflects the light from this virtual image, the convex mirror will still produce a virtual image, not a real one. **Conclusion for Reason (R)**: This statement is also false because a plane or convex mirror cannot produce a real image, even if the object is virtual. ### Final Conclusion Both the assertion (A) and the reason (R) are false. Therefore, the correct answer is that both statements are false. ### Summary of Steps: 1. Analyze the assertion about plane and convex mirrors producing real images. 2. Analyze the reason regarding virtual objects and real images. 3. Conclude that both the assertion and reason are false.
