Document Summary
Infinite because there is no radius of curvature. Just 1; there is no apparent change in the size in which the objects appear through images. Just like what we saw with example 3 from last class. The mirror is a concave mirror and the image is virtual. Convex mirrors: ray tracing still works; extrapolate rays to image, mirror equation still works, distance and height sign conventions the same, focal length sign is negative f = - (r /2) o. Example 4: a convex right-hand rear view mirror on a car, radius of curvature is 16. 0m. F = - r / 2 ; r = 16m f = -8m do =10m. Brain judges distances of the objects by size. Optical illusion makes individuals believe that the objects are farther away due to their decreased sizes but they are actually much closer. Example 5: you look into a shiny christmas tree ball (diameter 9. 0cm) from 30. 0 cm away.
