A 5.0-cm-high object is situated 17.0 cm in front of a concave mirror that has a radius of curvature of 10.0 cm. Use a ray diagram drawn to scale, measure the following. The mirror must be drawn to scale.
(a) the image distance (include the sign)
(b) the height of the image
The focal distance is ½ * radius of curvature
f = 5 cm
do = 17.0 cm
1/f = 1/do + 1/di
1/5 = 1/17 + 1/di
Multiply both sides by (5 * 17 * di)
17 * di = 5 * di + 5 * 17
Subtract 5 * di from both sides
12 di = 85
di = 85/12 = 7.08
The height ratio = the distance ratio
ho/hi = do/di
5.0/ hi =17/7.08
hi = 2.08

An object is placed in front of a convex mirror. Draw the convex mirror (radius of curvature 15 cm) to scale, and place the object 25 cm in front of it. Make the object height 4 cm. Using a ray diagram, locate the image and measure its height. Now move the object closer to the mirror, so the object distance is 5 cm. Again, locate its image using a ray diagram. As the object moves closer to the mirror, (a)...
