Question

Hold a magnifying glass over text and identify the distance where you can see the text bigger than they are written. Now move it away from the text. What do you notice? Which type of lens is a magnifying glass?

Show answer Hide answer
Answer
A magnifying glass is a convex lens.

Explanation

  • Held close, the text looks enlarged and erect.
  • Moved farther away, the text appears inverted.
  • This behaviour matches a convex (converging) lens.
The text enlarges up close and inverts when far, so a magnifying glass is a convex lens.
