An object is 12.0 cm from a converging lens (focal length = 15.0 cm). Determine the image magnification. Enter the numerical part of your answer to two significant figures

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.)

Photographs at a scale of S are required to cover an area X-mi square. The camera has a focal length f and focal plane dimensions of 9 × 9 in. If endlap is 60% and sidelap 30%, how many photos will be required to cover the area for the data given below? Part A: Express your answer as an integer. S=1:6800; X=10; f=152.4mm

True statements for optics Which of the following statements for single optic devices are true? Choose all that apply. It turns out that convex lenses always have a positive focal length. For real images, the image distance is negative and the object distance is positive. By convention, an inverted image has a positive image height. A magnification of -2 means the image is magnified. 0 Experiments have shown that converging optics can create virtual images. If an image has a magnification of -8, then the image is virtual. Which must be true? Using a single optic, an image with a negative image height is created. As a result, which of the following MUST be true? Choose all that apply. The image is real The image is virtual The image is inverted The image is upright The image distance is positive The image distance is negative The image has a positive magnification The image has a negative magnification The optic is converging The optic is diverging The optic has a positive focal length…

please help me answer the following

An object is placed 27 cm in front of a diverging lens having a focal length of magnitude 50 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.

Question 5. You have an optical system including 2 lenses with focal length fi and f2 and distance L between them. Calculate ABCD matrices for this system.

Please, step by step

Case 5: Object located in focus (d0= F'). The figure below shows an arrow-shaped object, placed in front of a convex lens at a distance d0 equal to a focal length (d0=F'). Draw the following rays in the figure: ray parallel to the optical axis, central ray. Don't forget to put the direction on each ray, both the incident rays and the transmitted rays. Label each ray with its name. Image characteristics for Case 5: Object located in focus (d0= F'). Choose the ones that apply: a) Virtual b) Real c) Inverted d) Increased e) No image is formed f) Equal size  g) Reduced h) Erect Case 6: Object located between the focus and the vertex of a convex lens (d0< F'). The figure below shows an arrow-shaped object, placed in front of a convex lens at a distance d0 less than a focal length (d0<F'). Draw the following rays in the figure: ray parallel to the optical axis, focal ray, central ray. Draw the image of the arrow, indicate in the same figure from where to where di is (image-lens…

Spherical refracting surfaces. An object O stands on the central axis of a spherical refracting surface. For this situation (see the table below, all distances are in centimeters), nį is the index of refraction where the object is located, n2 is the index of refraction on the other side of the refracting surface. Find (a) the image distance i, and determine whether the image is (b) real or virtual and (c) on the same side of the surface as object O or on the opposite side.
