“How can we create an artificial image of an object using light?”
As human beings, we are very visual creatures. We like to watch movies on big screens, take photographs of memorable events, and look at the stars of our universe using telescopes. Interesting enough, all of these technologies use one vital physical phenomena for their operation, real images. When light from an object passes through a thin concave lens, it will be focused onto a single point. At that single point, an image of the object will be formed. If placed on a planar surface, then this image will be visible for everyone to see! Real images are usually inverted, and their magnification depends on the distance from the object to the focal length of the lens
