cm
(b) Is the first image upright or inverted? (One submission.)
---Select--- inverted upright
(c) What is the height of the first image? Enter the value as a positive number.
mm
(d) The first image becomes the object for the second lens. What is the object distance, s2, for the second lens?
cm
(e) What is the distance, s'2, to the second image?
cm
(f) Is the second image upright or inverted (compared to the original object)? (One submission.)
---Select--- upright inverted
(g) What is the height of the second image?
mm
(h) What is the overall magnification of this two-lens system? Enter the value as a positive number.
Explanation / Answer
by lens equation
1 / f = 1 / u + 1 / v
1 / 2 = 1 / 2.17 + 1 / s'1
a) s'1 = 25.53 cm
height of image / height of object = -distance of image / distance of object
height of image / 0.036 = -25.53 / 2.17
height of image = -0.423 cm
since the height of the image is negative so,
b) image will be inverted
c) height of the image = 4.23 mm
object distance of second lens s'2
s'2 = L - s'1
s'2 = 83 - 25.53
d) s'2 = 57.47 cm
