Question

5. For objects placed (a) 30.0cm, (b) 10.0cm, and (c) 5.00cm in front of a diverging lens (whose focal points are 10.0cm away on either side of the lens), (i) locate the resulting image, (ii) compute the image’s magnification (state if it’s upright or inverted and whether it’s larger or smaller than the object), (iii) classify the image as real or virtual, and (iv)[Extra Credit] construct a careful, ray diagram (to scale) using the three principal rays to corroborate your answers. Use a ruler and protractor.

Answer #1

An
object is placed 5cm in front of a diverging lens of focal length
25 cm. A second converging lens of focal length 15cm is positioned
20 cm to the right of the first lens. What is the final image
distance? What is the magnification of the final image? Is it
upright of inverted? Real or virtual?

A diverging lens has a focal length of -14.0 cm. Locate the
images for each of the following object distances. For each case,
state whether the image is real or virtual and upright or inverted,
and find the magnification.

. Diverging lens 1 (focal length f1 = −20.0 cm) is placed a
distance of d = 45.0 cm to the left of diverging lens 2 (focal
length f2 = −15.0 cm). An object is placed p1 = 25.0 cm to the left
of diverging lens 1 and has a height of h = 16.0 cm.
(a) Where is the image formed by diverging lens 1 (i.e. what
is q1)? What is this image’s height and is it upright or...

An object is placed 78.1 cm in front of a diverging lens with a
focal length of magnitude 37.3 cm. A converging lens having a focal
length of magnitude 27.49 cm is placed 105.3 cm past the first
lens. Where is the final image formed. Is this image Real or
Virtual. Inverted or Non-Inverted? Also calculate the
magnification.

Question: An object is placed 10 cm in front of a diverging

A diverging lens has radius of focal length f = –10.0
cm. An object is placed a certain distance dO from the mirror along
its principal axis.
For each value of dO in the table, fill in (i) the
distance dI from the lens to the image; (ii) the lateral
magnification m of the image; (iii) whether the image is real or
virtual; (iv) whether the image is on the same side of the lens as
the object or the...
