image size in a mirror mastering physics

The cartesian sign convention is used here. Since the lenses are 75 cm apart, the image formed 46.7 cm to the right of lens 1 is located 28.3 cm to the left of lens 2 so the object distance, then, is. If an object is placed inside the focal length of a concave mirror, and enlarged virtual and erect image will be formed behind the mirror. This image (which is real, inverted, and enlarged) becomes the object for the second lens as we again apply the Image Equation, or. If the object is outside the focal length, a concave mirror will form a real, inverted image.

The virtual image that is formed will appear smaller and closer to the mirror than the object. Using a ray parallel to the principal axis and one incident upon the center of the mirror, the position of the image can be constructed by back-projecting the rays which reflect from the mirror.

A third useful ray is that through the center of curvature sinceit is normal to the mirror and retracesits path backward.Ī convex mirror forms a virtual image.The cartesian sign convention is used here. Mirror ray tracing is similar to lens ray tracing in that rays parallel to the optic axis and through the focal point are used. Ray Diagrams for Mirrors Mirror Ray Tracing
