Question

A) A 2.0-cmcm-tall object is 16.5 cmcm in front of a diverging lens that has a -25 cmcm focal length.

1. Calculate the image position.

2. Calculate the image height.

B) A 2.0-cmcm-tall object is 12 cmcm in front of a concave mirror that has a 25 cmcm focal length.

1. Calculate the image position.

2. Calculate the image height.

C) A slide projector needs to create a 90-cmcm-high image of a 2.0-cmcm-tall slide. The screen is 290 cmcm from the slide.

1. What focal length does the lens need? Assume that it is a thin lens.

2. How far should you place the lens from the slide?

Answer #1

A 3.0-cm-tall object is 15 cm in front of a diverging mirror
that has a -25 cm focal length.
Part A
Calculate the image position.
Part B
Calculate the image height.

A 1.0 cm tall object is 2.0 cm in front of a converging lens
with a focal length of 3.0 cm.
A. Determine the image position and height by using ray tracing
to find image
B. Calculate the image position and height

A 3.0-cm tall object is 45 cm in front of a diverging mirror
that has a -25 cm focal length. Calculate the image position and
height. Explain it using a diagram, the equation used in symbol
form, and then substitute the values in:

A 2.0 cm tall object is 25.0 cm in front of a concave mirror
that has a 10.0 cm focal length. (a) Draw a ray diagram showing the
object and image position. (b) Where is the image located? (16.6
cm) (c) What is the height of the image? (-1.32 cm) (d) What are
the characteristics of the image?

a 2.5 cm tall object is 15cm in front of a concave
mirror that has a 25cm focal length
calculate the image position and height

A 76 cm tall object is placed 238 mm in front of a diverging
lens with a focal length of magnitude 650 mm.
Find the location of the image. di = mm
Find the magnification of the image. M =
Find the image height. hi = mm

An object is placed in front of a diverging lens whose focal
length is - 27.0 cm. A virtual image is formed whose height is
0.516 times the object height. How far is the object from the
lens?

A converging lens with a focal length of 20 cm and a diverging
lens with a focal length of -34 cm are 74.0 cm apart. A 2.6-cm-tall
object is 40 cm in front of the converging lens.
1. Calculate the distance between image and diverging lens.
2. Calculate the image height.

A diverging lens with a focal length of -13 cmcm is placed 11
cmcm to the right of a converging lens with a focal length of 22
cmcm . An object is placed 36 cmcm to the left of the converging
lens. a) Where will the final image be located? b)Where will the
image be if the diverging lens is 55 cmcm from the converging
lens?Find the image location relative to the diverging lens.

A 3.0-cm-tall object is 45 cm in front of a converging mirror
that has a 25 cm focal length.
