Drawing light reflections in Geometry Sketchpad may be confusing to some people. PHP editor Banana will guide you step by step through the required operations in this article. The following will detail how to create incident rays, reflected rays, normals, and other necessary elements, as well as how to use the tools and features of the Geometry Sketchpad to complete the entire process. Read on to learn more about how to simulate the reflection of light in this powerful geometry software.
Draw the reflective surface. Open the Geometry Sketchpad, select the [Line Segment Tool] on the left sidebar, click once in the right working area to determine an endpoint of the line segment, then hold down the Shift key, drag the mouse to the right, and click at the appropriate location to draw Draw line segment AB,
Take the midpoint C of line segment AB and draw a perpendicular line. Select the line segment AB, click the [Construction] menu in the upper menu bar, and select the [Midpoint] command from its drop-down option, so that the midpoint C of the line segment AB is obtained. Select point C and line segment AB, click the [Construction] menu on the upper menu bar, and select the [Perpendicular Line] command from its drop-down option, thus obtaining the perpendicular line of line segment AB.
With C as the endpoint, draw a ray. Select the [Ray Tool] on the left sidebar, click point C with the mouse, then drag the mouse to the upper right and click at the appropriate position to create a ray L, which can be used as a reflected light.
Do the incident light. Double-click the vertical line of line segment AB to mark the mirror surface with the mouse, then select ray l, click the [Transform] menu on the upper menu bar, and select the [Reflection] command from its drop-down option, thus obtaining the incident ray.
