📚 Step Guide

Draw the Principal Axis

Begin by drawing a horizontal line - this is the principal axis. It represents the path that light travels along when passing through the center of the lens.

Key Points:

Draw a straight horizontal line across the canvas
The axis should extend beyond the lens on both sides
This line is your reference for all measurements
Use the grid to help you draw straight lines

Formula Reference:

The principal axis is the reference line for measuring object distance (u), image distance (v), and focal length (f).
