The chromosomes become visible under a light microscope during prophase stage of mitosis

Explanation:

Propohase -

The first phase of mitosis, in which the chromosomes becomes visible, as a distinct structure, the nuclear envelope breaks down and the spindle formation takes place.

Hence, this stage is visible under the light microscope.

The next phase is the metaphase, in which the chromosomes line up in middle of cell.

In the third phase, i. e., the anaphase, the chromosomes moves towards the opposite sides of the vcell.

In the fourth phase, i. e., the telophase, the two nuclei are formed.

In the last stage, i. e., cytokinesis, the cell finally divides into two daughter cells.
