A real image is usually inverted, but can be upright in special cases. True or false?
False.
A real image is typically formed when light rays converge after passing through a lens or reflecting off a mirror. In most cases, when an object is placed in front of a lens or mirror, the image formed on the opposite side will be inverted, meaning it appears upside down compared to the actual object.
However, there are certain special cases where a real image can be upright. One example is when the object is placed between the focal point and the lens/mirror. In this scenario, the rays of light diverge after passing through the lens/mirror and form an upright image on the same side as the object. This is called a magnified virtual image. Another case is when using a combination of lenses or mirrors that counteract the inversion effect, resulting in an upright real image.
To understand whether a real image is inverted or upright, you can follow these steps:
1. Determine the position of the object relative to the lens or mirror.
2. Identify the focal point(s) of the lens or mirror.
3. Trace the path of a few light rays from the object to the lens/mirror.
4. Observe where these rays intersect after passing through or reflecting off the lens/mirror.
5. Analyze the orientation of the image formed by considering the intersections of the rays.
By following these steps and understanding the basic principles of optics, you can determine whether a real image is usually inverted or can be upright in special cases.
