What distinguishes real images from virtual images?

• A. Real images can be projected onto a screen, while virtual images cannot
• B. Real images are smaller than the object, while virtual images are larger
• C. Real images are always upside down, while virtual images are always upright
• D. Real images cannot be formed by converging light rays

Answer: (A)

Real images and virtual images are distinguished primarily by their ability to be projected onto a screen. A real image is formed when light rays converge and can be captured on a surface, allowing it to be projected. This means that real images can be represented in a tangible way, such as on a movie screen or wall, where light from the image passes through and reaches the observer’s eyes. In contrast, virtual images occur when light rays appear to diverge from a point. They cannot be projected onto a screen because the light does not actually converge at the location of the image. A common example of a virtual image is the one created by a flat mirror, where the image can be seen but cannot be projected onto another surface. While size comparison and orientation (upright or inverted) of images can vary based on the characteristics of the optical system involved, these factors do not serve as definitive distinctions between real and virtual images. Therefore, the ability of real images to be projected onto a screen sets them apart from virtual images.
