A small toy of height 3.5 cm is placed 30 cm away from a converging lens. A real image is formed 20 cm away on the other side of the lens. Determine: 1) the focal length; 2) the magnification; 3)the image height.
Find the focal length of a converging lens that produces a focused real image 3 cm from the lens of an object that is 7 cm from the lens. Draw a ray diagram for this configuration.

A small object is placed 25.0 cm from a converging lens of focal length 40.0 cm. The object is to the left of the lens. Where is the image? A- 17cm to the right of the lens B- 25cm to the left of the lens C- 17 cm to the left of the lens D-25 cm to the right of the lens E-67cm to the right of the lens F-67 cm to the left of the lens A small object...
A 4.0cm tall object is placed 60cm away from a converging lens of focal length 30 cm. What is the nature and location of the image?
An object is placed 30 cm to the left of a converging lens of focal length f1= + 20 cm. A second lens sits 40 cm to the right of the first lens. The two - lens system produces an overall magnification of M = + 2.0. What is the focal length (f2) of the second lens?
a small object is placed 25.0 cm from a converging lens of focal length 40.0cm.the object is to the left of the lens where is the image? same as the previous question. which statement is true about the image? It is real, upright and larger than the object It is virtual, upright and larger than the object. It is virtual, inverted and larger than the object. It is virtual, inverted and smaller than the object. It is real, inverted and...
A converging lens with a focal length of 70.0cmforms an image of a 3.20-cm-tall real object that is to the left of the lens. The image is 4.50cm tall and inverted. c-) How much to the left of the lens is the object? Express your answer with the appropriate units.
An object is placed 20 cm from a converging lens with focal length 15 cm. A concave mirror with focal length 10 cm is located 75 cm to the right of the lens asshown in the figure. Note: The figure is not drawn to scale. A)Determine the location of the final image.B)If the height of the object is 1.0 cm, what is the height of the image?thanks!
20. An object is placed 100 cm in front of a converging lens of focal length 20 cm. If the height of the object is 6.0 cm, what is the height of the final image? a. 0.75 cm b. 1.5 cm c. 3.0 cmm d. 25.0 cm e. None of the above
