Why does a convex lens magnify and a convex lens does not?
What is a virtual image?
In this video I cover the difference between the two lens types and how they produce virtual images.

If you can see through concave lens, why the light does not form on the screen. Why virtual image don't form on the screen. pls help

Because for a real image the all light paths from any one point on an object must pass through and meet on the other side. This is an extra requirement for real image formation that only happens in convex lenses.

So, in order to form the "image" on the screan, the light must be focus enough and bright enough to form on the screen? And light passing through concave lens isn't bright enough and doesn't form a image on the screen. Am I right?
