In the figure, the image is viewed on a screen and is 13.5 mm tall. What is the focal length of the lens? Please show work,
A: +124 cm
B: +14.6 cm
C: -89.3 cm
D: +20.4 cm
E: -14.6 cm
h'/h=s'/s
(s)(h'/h)=s'
(35)(1.35/.97)=48.71=s'
then use: (1/s)+(1/s')=(1/f)
(1/35)+(1/48.71)=1/f
=+20.4

A slide projector needs to create a 98-cm-high image of a 2.0-cm- tall slide. The screen is 300 cm from the slide. Assume the image is projected through a thin lens. To get that type of image, what type of lens do we need, and is the focal length positive or negative? > Converging, Positive Diverging, Negative Diverging, Positive Converging, Negative
- Consider a camera that uses a lens with a focal length of 35 mm. How far behind the lens must the film be in order to take a picture of a flower that is 75 cm in front of the lens? - A convex lens is used to make an image of a 10 cm tall arrow on a screen. The arrow sits 25 cm in front of the lens and the image that it creates is 20 mm...
