Please solve this problem, I want to check if my
answers are correct:
use the formula sheet provided below
My answers:
a- Si(1) = 222 cm
b- So(2) = 210 - 185 = 25 cm
c- Si(2) = - 16.25 cm
d- M = - 1.182
Problem 5 (20 points) For the parts of the below question, fill in the empty boxes with your answer (YOUR ANSWER MUST BE ONLY A NUMBER; DO NOT WRITE UNITS; DO NOT WRITE LETTERS). A thin biconvex lens (labelled in the figure) having a focal length of 74 cm is located at a distance d = 210 cm in front (i.e, to the left) of a thin biconcave lens (labelled L2 in the figure) of focal length 74 cm, as shown in the figure L2 ܝܪ Pencil So1 d A pencil is situated at a distance 5,1 = 111 cm to the left of the positive lens. We will denote this pencil by "OBJECT 1". a) (5 points) The image of the pencil formed by Ll is located at a distance si from Ll. Calculate 811- 8,1 = cm b) (5 points. The previous image from part a) is now treated as the object of L2 We will denote this object by "OBJECT 2". Assume 811 = 185 cm and determine the distances between "OBJECT 2" and L2 8.2 = c) (5 points] Consider 32 = 20.83 cm. The image of "OBJECT 2* formed by L2 is located at a distance s from L2.
