Real Images

In an experiment to find the focal length of a convex lens, we place the object needle on the one side of the lens and tries to set the image needle on the other side of the lens such that the inverted object needle and the image needle moves tip to tip when we move our eyes laterally. Here's the question: How we are able to see the inverted real image of the object needle without any screen?

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

It will be formed at focus

Actually the image formed is inverted and real . But real image require a screen to be seen. So how can we see the real image without any screen?
