- Consider the optical system shown in the figure. The lens and mirror are separated by d = 1.00 m and have focal lengths of f₁ = +87.5 cm and f₂= = -53.4 cm, respectively. An object is placed p = 1.00 m to the left of the lens as shown. Lens LL -1.00 m Object distance location (a) What is the distance (in cm) and location of the final image formed by light that has gone through the lens twice? (Give the magnitude of the distance and select its location with respect to the lens.) ---Select--- -1.00 m- cm Mirror (b) Determine the overall magnification of the image. (c) State whether the image is upright or inverted. upright invertedA virtual image of magnification +0.5 is produced when an object is placed 10 cm in front of a curved mirror. Determine the radius of curvature of the mirror.A doctor is examining a mole using a magnifying glass of focal length 15 cm. The lens is held 13.5 cm from the mole.

Find the radii of curvature and the focal length of the lens.An object is placed 27 cm in front of a diverging lens having a focal length of magnitude 65 cm. What is the image distance, in cm
- A lens forms an image of an object. The object is 16.0 cm from the lens. The image is 12.0 cm from the lens on the same side as the object. (a) What is the focal length of the lens? Is the lens converging or diverging? (b) If the object is 8.50 mm tall, how tall is the image? Is it erect or inverted? (c) Draw a principal-ray diagram.Using a single optic with a positive focal length, an image 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 O The image is upright The image distance is positive The image distance is negative The image height is positive The image height is negative The image has a positive magnification The image has a negative magnification The optic is converging The optic is divergingAn object is placed 40 cm in front of a thin lens. If an image forms at a distance 120 cm from the lens, on the same side as the object, what is the focal length of the lens, 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.
