a) What is the object distance?
b) What is the image distance
c) What is the focal length of the lens from the lens equation ?
d) What is the expected magnification from equation ?
A second lens, with f=5 cm, is placed 40 cm from the lamp.
e) What is the distance s, between the two lenses?
f) What is the distance dobj2 from the first image to the second lens?
g) Compute the expected second image distance from equation (1). This is the distance from the second lens to the second image.
g) What is the distance of the second image from the lamp?
