What is the phenomenon of image formation by concave mirrors?

• A. Concave mirrors produce only virtual images regardless of the object's distance
• B. Concave mirrors can produce real or virtual images depending on the object's distance
• C. Concave mirrors can only produce inverted images
• D. Concave mirrors cannot produce any images

Answer: (B)

Concave mirrors are unique in their ability to form both real and virtual images, which depends largely on the position of the object in relation to the mirror's focal point. When an object is placed beyond the center of curvature of the concave mirror, the image formed is real, inverted, and smaller than the object. If the object is located between the focal point and the mirror, however, the image will be virtual, upright, and larger than the object. This versatility is a result of the way concave mirrors reflect light. They focus parallel rays of light that strike their surface to a point known as the focal point, creating varying image characteristics based on the object's distance from the mirror. Thus, the ability to produce both types of images—real and virtual—based on an object's position is what makes concave mirrors particularly useful in various applications, such as in telescopes and makeup mirrors.
