The difference between virtual image and real image
1, reason: the real image is formed by the convergence of the actual light, and the virtual image is formed by the convergence of the reverse extension line of the actual light. That is to say, the real image is an image formed by the convergence of the actual light after passing through a lens or other optical elements, and the virtual image is an image formed by the convergence of the actual light and the reverse extension line.
2. Position: the position of the real image is the point where the actual light converges, and the position of the virtual image is the point where the actual light is converged by the reverse extension line. Therefore, the real image is usually located behind the lens or other optical elements, while the virtual image is usually located in front of the lens or other optical elements.
3. Optical screen acceptance and physical application: the real image can be accepted by the optical screen, but the virtual image cannot. Because the real image is the convergence of the actual light and can be projected on the screen, while the virtual image is the convergence of the reverse extension line of the actual light and cannot be projected on the screen. In physical applications, real images are usually used in photography, projection and other occasions that need to truly reflect objects, while virtual images are mostly used in optical instruments.
4. Visual effect: the visual effect of the real image is the same as that of the real object, and the visual effect of the virtual image is the opposite. For example, when taking pictures, the main body of the real image is clear and the virtual image is blurred; When viewed under a magnifying glass, the observed object of the real image is enlarged, while the virtual image is reduced.
Influence of Virtual Image and Real Image on Environment
1. Visual environment: Both real images and virtual images will affect people's visual experience. Real images can provide more realistic visual effects and make people feel the actual existence of objects, while virtual images can create an illusion or virtual visual effects and change people's perception of the size, shape and color of objects. For example, photography, real images can capture the details and colors of objects.
2. Psychological environment: Real images and virtual images will also affect people's mood and emotions. Real images can make people feel the real world and bring a sense of sureness and trust, while virtual images can create a sense of mystery or fantasy and arouse people's imagination and desire for exploration. For example, in movies, real images can create real scenes and characters, making it easier for viewers to produce * * * songs and emotional * * * songs.
3. Physical environment: Real images and virtual images have little influence on the physical environment, but in some cases, they will also have certain influence. For example, in optical instruments, real images can be enlarged or reduced by optical elements such as lenses or reflective surfaces, while virtual images can be deformed or distorted by optical elements. In photography, the real object is affected by light, and the virtual image is not directly affected by light.
4. Socio-cultural environment: Real images and virtual images will also have a certain impact on the socio-cultural environment. Real images can reflect social reality and cultural background. For example, photos and portraits can record historical events and cultural heritage, while virtual images can reflect the imagination and creativity of society. For example, movies and games can create unique virtual worlds and cultures.
