Question
The concave mirror shown above has a focal length of 24 centimeters. An object 2 centimeter high is placed 15 centimeters in front of the mirror.a. Using at least two principal rays, locate the image on the diagram above. Draw a ray diagram for the above problem. It is recommended that you redraw your own diagram for the measurements given above. The curve for the mirror should be done using a compass with radius equal to twice the focal length. You may scale down your diagram. Just indicate your scale beside diagram.
c. Calculate the distance of the image from the mirror. cm
d. Calculate the height of the image. cm
Explanation / Answer
F=24cm U=15cm 1/v=1/f-1/u=>v=-40cm d. Calculate the height of the image. Cm magnification=v/u=40/15=8/3 height of the image=8/3*2=16/3cm
