Question
Please show step by step.
what i have so far
m = -si/ so = -i /o
1/f = 1/di + 1/do
DIRECTIONS: Work the problem. You must show all work to receive credit, and you must return this sheet. If you have to construct a graph, use the graph paper provided in the laboratory. A student set up a magnetic optical bench with the crossed arrow target at 22.7 cm. When a concave mirror is placed at 65.2 cm, an inverted image that is 3/4 as tall as the object is formed, (a) Where is the image located? (b) What is the focal length of the mirror?
Explanation / Answer
-S'/S = I/O = -3/4 ................
S" = 3S/4 = 17.03 cm
1/S + 1/S' = 1/F
1/S + 4/3S= 1/F
7/3S = 1/F
F = 3S/7 =9.73 cm
