Question

A converging lens has a focal length of 14.5 cm . For each of two objects located to the left of the lens, one at a distance of s1 = 23.0 cm and the other at a distance of s2 = 8.00 cm , determine the following.

Part A

Determine the image position.

Enter your answer as two numbers separated with a comma to three significant figures.

Part B

Determine the magnification.

Enter your answer as two numbers separated with a comma to three significant figures.

Part C

Determine whether the image is real or virtual.

Part D

Determine whether the image is upright or inverted.

Explanation / Answer

Given data
f= 14.5 cm
1st object at do = 23cm
2nd object at do = 8cm
Part A
Determine the image position.
1/f 1/do+1/di
for 1st object
1/14.5 = 1/23 + 1/di
di = 39.235 cm
for 2nd object
1/14.5 = 1/8 + 1/di
di = -17.846 cm
= 39.235,-17.846

Part B
Determine the magnification.
magnification is M = -do/di
M1 = -23/39.235 = 0.586
M2 = 8/17.846=0.448
0.586,0.448

Part C
Determine whether the image is real or virtual.
1st image is real
1st image is virtual

Part D
Determine whether the image is upright or inverted.
1st image is inverted
1st image is upright
