Section Problems
Section 0 - Introduction
0.1 Use the simulation in the interactive problem in this section to answer the following questions. (a) Where must the object be
relative to the focal point F to create an image on the same side of the lens as the object? (b) Where must the object be to
create an image on the opposite side of the lens? (c) Where must the object be to create an upright image?
(a) i. On the opposite side of the focal point as the lens.
ii. Between the focal point and the lens.
iii. It is impossible.
iv. Anywhere.
(b) i. On the opposite side of the focal point as the lens.
ii. Between the focal point and the lens.
iii. It is impossible.
iv. Anywhere.
(c) i. On the opposite side of the focal point as the lens.
ii. Between the focal point and the lens.
iii. It is impossible.
iv. Anywhere.Section 4 - Interactive problem: image with a diverging lens
4.1 Use the simulation in the interactive problem in this section to answer the following questions about a single object and a
diverging lens. (a) Is it possible to make a real image? (b) Is it possible to make an inverted image? (c) Is it possible to make
an image that is larger than the object?
(a) Yes No
(b) Yes No
(c) Yes NoSection 7 - Lens equations
7.1 An object is placed 23.0 cm in front of a thin lens. The image created is 5.00 cm behind the lens. (a) Is the object distance
positive or negative? (b) Is the image distance positive or negative? (c) What is the focal length of the lens? (d) Is the lens
converging or diverging?
(a) Positive Negative
(b) Positive Negative
(c) cm
(d) Converging Diverging
7.2 An object is placed 23.0 cm in front of a thin lens. The image created is 5.00 cm in front of the lens. (a) Is the object distance
positive or negative? (b) Is the image distance positive or negative? (c) What is the focal length of the lens? (d) Is the lens
converging or diverging?
(a) Positive Negative
(b) Positive Negative
(c) cm
(d) Converging Diverging
7.3 The focal length of a thin lens is 0.110 m. You want to use it to produce a real image at 0.600 meters from the lens. How far
from the lens should the object be placed?m
7.4 The focal length of a thin lens is í9.00 cm. You place an object 15.0 cm from the lens. (a) Is the image produced real or
virtual? (b) What is the image distance (include the correct sign)?
(a) Real Virtual
(b) cm(^624) Copyright 2000-2007 Kinetic Books Co. Chapter 33 Problems
