An object (height = 5.0 cm) and its image are on opposite sides of a converging lens. The object is located 11.0 cm from the lens. The image is located 5.3 cm from the lens. Determine the image height (in cm). Enter the numerical part of your answer to two significant figures. Hint: Remember that the sign of the image height is significant.

You have a thin, diverging lens. If the value of q (the distance from the image to the mirror along the principal axis of the mirror) is -3.57cm and the distance of p (the distance from the object to the mirror along the principal axis of the mirror) is 17.16cm, what is the focal length of the diverging lens? Object Ray 1 Principal focal point Virtual image Diverging lens. Ray 1 Ray 3 Ray 2 Secondary focal point Note: Do not explicitly include units in your answer (it is understood the unit is cm). Enter only a number. If you do enter a unit, your answer will be counted wrong.

An object is held 33.5 cm from a convex mirror. It creates a virtual image of magnification 0.253 What is the image distance? (Mind your minus signs.) (Unit = cm)

A 2.30 cm tall object is 22.0 cm to the left of a lens with a focal length of 11.0 cmcm . A second lens with a focal length of 33.0 cm is 44.0 cm to the right of the first lens. Part A Calculate the final image location from the second lens.         i2=   cm     Part B Calculate the image height.         h(i) =   cm

A convex lens produces a real, inverted image of an object that is magnified 2.5 times when the object is 20 cm from the lens. a) What is the image distance of the lens? di = b) What is the focal length of the lens? f =

Shown in the figure below is a system containing two lenses and an object. The focal lengths of the two lenses are f1 = -19 cm and f2 = 9.5 cm. The two lengths indicated in the figure are L1 = 28.5 cm and L2 = 15.2 cm. Determine all the following about the image from the first lens only:Object distance for the first lens, d01.  cmImage distance for the first lens, di1.  cmMagnification of the first lens, m1. The second lens uses the image from the first lens as its object. Determine all the following about the image from the second lens:Object distance for the second lens, d01.  cmImage distance for the second lens, di1.  cmMagnification of the second lens, m1. Determine the magnification of the whole system, mtot. Select the correct attributes of the final image of the system: virtual real     enlarged shrunk     upside down right side up

An object is placed 36 cm in front of a converging lens with a focal length of 20 cm. Draw a ray diagram.   Estimate the image distance (in cm). (Give your answer as a distance from the center of the lens.) ________ cm

One positive lens (focal length = f1) and one negative lens (focal length = -f2) are placed at a distance d. – All lenses are thin lenses. Find the overall ABCD matrix of the system Find the value of d when “C” of the overall matrix is zero. ( Hint : Find d in terms of f1 and f2) (This is when the focal length of the overall system is infinity.)

Shown in the figure below is a system containing two lenses and an object. The focal lengths of the two lenses are f₁ = 17 cm and f₂ = -8.5 cm. The two lengths indicated in the figure are L₁ = 25.5 cm and L2 = 13.6 cm. 41 f1 L₂ f2 Determine all the following about the image from the first lens only: Object distance for the first lens, do1.

An object is placed 30 cm in front of a diverging mirror having a focal length of magnitude 20 cm. What is the image distance, in cm?  Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
