This simulation looks at the reflection of multiple incident rays from a concave spherical mirror. The rays are reflected back from the mirror so that the angle of incidence and the angle of reflection are the same. [br][list][*]Move the slider to change the radius of the mirror.[/*][*]Individual rays can be turned on or off using the check boxes on the left hand side. [/*][*]You can choose to display the normals for each ray by checking the appropriate checkbox.[/*][*]You may also display the shape of a parabolic mirror with the same focal length.[/*][/list]
