The correct Answer is:
To solve the given question, we will analyze the assertion and the reason separately. ### Step 1: Analyze the Assertion The assertion states that "Reflected image always travels in opposite direction of the object." 1. **Understanding Reflection**: When light rays hit a reflective surface, they bounce back according to the law of reflection, which states that the angle of incidence is equal to the angle of reflection. 2. **Direction of Travel**: If we consider an object placed in front of a mirror, the light rays emanating from the object travel towards the mirror and reflect back. The reflected rays appear to originate from a point behind the mirror, which is the location of the virtual image. 3. **Conclusion on Assertion**: The assertion is generally true for real images formed by mirrors, as the reflected rays travel in the opposite direction to the incoming rays. However, for virtual images (like those formed by a plane mirror), the rays appear to come from behind the mirror, which means they are in the same direction as the object. Therefore, the assertion is **false**. ### Step 2: Analyze the Reason The reason states that "Speed of point image formed by reflected rays is always equal to the speed of its point object." 1. **Speed of Light**: The speed of light in a vacuum is constant, approximately \(3 \times 10^8\) m/s. This speed does not change whether the light is traveling towards an object or reflecting off a surface. 2. **Image Formation**: When light reflects off a surface, the speed of the light rays remains constant. Thus, the speed of the light rays that contribute to the formation of the image is equal to the speed of the light rays coming from the object. 3. **Conclusion on Reason**: Since the speed of light is constant and does not change upon reflection, the reason is **true**. ### Final Conclusion Based on the analysis: - The assertion is **false**. - The reason is **true**. Thus, the correct answer is that the assertion is false while the reason is true.
