Following are the precautions while making the image by the help of convex lens:

1) Fix the convex lens vertically in the lens holder.

2) The base of the lens and white screen should be in a line with the measuring scale.

3) Record the position of the lens and screen only when a well-defined sharp image is formed.

4) There should not be an obstacle in the path of the convex lens.
