Question
1. An object with a height of 42 cm is placed 2.2 m in front of a concave mirror with a focal length of 0.45 m. Find the location and magnification of the image produced by the mirror, using the mirror and magnification equations.
d=_________m
M=_________
2. An object with a height of 42 cm is placed 2.3 m in front of a convex mirror with a focal length of -0.57 m. Find the location and magnification of the image produced by the mirror using the mirror and magnification equations.
If you could show your work that would be awesome! Thank you!!
d = m M =Explanation / Answer
An object is placed at a distance do = 2.2 m
focal length f = 0.45 m
a ) 1/ f = 1/ di +1/ do
1 / 0.45 m = 1/ di + 1/ 2.2 m
distance of the image is di = 0.57 m
------------------------------------
magnification of the image is m = - di / do
= - 0.57 m / 2.2 m
= -0.259 m
-----------------------------------------------------
b)The mirror equation is
1/f = 1/p + 1/q
1/-0.57 = 1/2.3 + 1/q
q = -0.457 m (image is in back of the mirror)
----------------------------------
The magnification = -q/p
M = -(-0.457) / (2.3)
M = 0.199
