(a)
focal length f = 62 cm
object distance p = 62 cm
image distance q = ?
1/p + 1/q = 1/f
1/62 + 1/q = 1/62
q = infinity
m = infinity
answer
q = 0
M = 0
no image
______________
(b)
focal length f = 62 cm
object distance p = 12.4 cm
image distance q = ?
1/p + 1/q = 1/f
1/12.4 + 1/q = 1/62
q = -15.5 cm
m = -q/P = 15.5/12.4 = 1.25
answer
q = 15.5
M = 1.25
virtual
upright
++++++++++++++++
(c)
focal length f = 62 cm
object distance p = 186 cm
image distance q = ?
1/p + 1/q = 1/f
1/186 + 1/q = 1/62
q = 93 cm
m = -q/P = -93/186 = -0.5
answer
q = 93
M = 186
real
inverted
