Find the focal length of a concave mirror if an object 17 cm from the mirror has a virtual image 2.6 times the object's actual size.
Express your answer in cm using two significant figures.
magnification m = +2.6
m = -s'/s
-s'/s = +2.6
s' = -2.6*s = -2.6*17
from lens equation
1/s + 1/s = 1/f
1/17 - 1/(17*2.6) = 1/f
f = 27.6 cm

A concave mirror of 5 cm focal length and a convex mirror of also 5 cm focal length are 30 cm apart. An object positioned 15 cm from the concave mirror. Let the image first formed by the concave mirror be the object for the convex mirror. Determine the location, orientation, nature (virtual, real), and magnification of the final image formed by the convex mirror.
A 2.5-cm-tall object is 10 cm in front of a concave mirror that has a 25 cm focal length. Part A: Calculate the image position. Express your answer to two significant figures and include the appropriate units. Part B: Calculate the image height. Type a positive value if the image is upright and a negative value if it is inverted. Express your answer to two significant figures and include the appropriate units.
