Strålgång vid konvexspegel

Flytta röda objektet med musen. En konvex spegel bildar alltid en rättvänd, förminskad virtuell bild (som visas som grått till höger om spegeln)
This applet shows the basics of the Convex Mirror.
The yellow lines represent the three rays of light needed to form the image are as follows:
One comes from the object and travels parallel to the principal axis and therefore appears to originate from the focal point F after reflection from the mirror.
The second ray heads toward F, emerging parallel to the principal axis after reflection.
The third ray travels toward the center of curvature C; as a result it strikes the mirror perpendicularly and reflects back on itself.
The green lines are the virtual rays as they appear to an observer.
The gray lines are light rays.
The red arrow is the object and the gray arrow is the resulting virtual image. You can move the object by either draging it or by clicking to the location of your choice.
