What is the difference between real and virtual images?

• A. Real images are upright; virtual images are inverted
• B. Real images can be projected onto a screen; virtual images cannot
• C. Real images are always smaller than virtual images
• D. Real images are created by lenses only

Answer: (B)

The distinction between real and virtual images primarily revolves around their ability to be projected and their nature in relation to the light rays. Real images are formed when light rays converge and can be projected onto a screen, which allows for them to be captured and displayed. This often occurs with concave lenses or mirrors when objects are located beyond the focal point. Real images are typically inverted and can vary in size depending on the object's distance from the lens or mirror. In contrast, virtual images arise when light rays appear to diverge from a specific point, meaning they cannot be projected onto a screen since the light does not actually converge at that location. An everyday example of a virtual image is the reflection seen in a flat mirror, where the image appears behind the mirror but cannot be captured on a physical surface like a screen. This concept is crucial in understanding optical systems, where the behavior of light in various configurations (like different types of lenses and mirrors) determines whether the resulting image is real or virtual.
