An object is 20 cm in front of a converging lens with focal length f1. The produced image has a magnification of -0.75. Now it is replaced by another converging lens with focal length f2, leaving the object at the same distance of 20 cm. The new image has a magnification of -1.40. Show that the ratio of focal lengths f2 / f1 = (7/6) ^2
An object 2.02 cm high is placed 40.2 cm to the left of a converging lens having a focal length of 30.5 cm. A diverging lens with a focal length of-20.0 cm is placed 110 cm to the right of the converging lens. (a) Determine the position of the final image. distance location to the right , of the diverging lens (b) Determine the magnification of the final image 128.4 Your response differs from the correct answer by more than...
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?
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!
An object is placed 19 cm to the left of a converging lens of focal length 29 cm. A diverging lens of focal length 8 cm is 25 cm to the right of the converging lens. Find the position and magnification of the final image.
A Lens and a Mirror
In the figure below a converging lens is located at 0
cm. It has a focal length of f1 = 20.2
cm. An object is placed at a = 25.2 cm to the
left from the converging lens. In addition a concave mirror with
focal length of f2 = 10.4 cm is located L = 117.21
cm to the right of the lens.
1) Give your final answers in a coordinate system which has its...
A converging lens has a focal length of 7.5 cm. An object is placed 5 cm from the lens. a. Draw the rays tracing diagram to locate the image. Is the image real or virtual? b. Calculate the location and the magnification for this image.
An object is placed 45 cm to the left of a converging lens of focal length 17 cm. A diverging lens of focal length −29 cm is located 11 cm to the right of the first lens. (Consider the lenses as thin lenses). a) Where is the final image with respect to the second lens?cm b) What is the linear magnification of the final image?
An object is placed in front of a converging lens with a focal length of 21.2 cm. For each object distance, find the image distance and the magnification. Describe each image. (a) 42.4 cm: location cm magnification (b) 10.6 cm: location cm magnification
An object is placed 46cm in front of a converging lens of focal length 5cm. Another converging lens of focal length 11cm is placed 31cm behind the first lens. a) Find the position of the final image with respect to the second lens. b) Find the magnification of the final image.
