Question
In this diagram we have a concave mirror with a curvature R=37 cm.
We place an object that has a height h= 5.7cm and a distance s= 27cm from the mirror.
a. What is the focal length of the mirror?
b. Where will the image be located s'?
c. What is the magnification m?
d. Is the image real or inverted?
f. Draw a ray diagram of the figure above to illustrate the position and orientation of the image. You will need 2 rays to do this.
In this diagran w Curva have a concave .cedeR:37cr. e place anchect that has ahey e placeanobjeExplanation / Answer
(a)
R = 37 cm
Focal length, f = R/2
f = 37/2
f = 8.5 cm
(b)
do = 27 cm
f = 8.5 cm
di = ?
we know,
1/f = 1/di + 1/do
1/8.5 = 1/di + 1/27
di = 12.41 cm
(c)
M = -di/do
M = -12.41/27
M = - 0.459
(d)
Image is Inverted & Real !!
