An image formed by a convex mirror has a size h' = +5 cm. knowing that %3D the object has a height h > 0, which of the following statements is true?

The Sun subtends an angle of 0.533° at a distance of 1 astronomical unit, which is 1.496 ✕ 1011 m, the average Sun–Earth distance.   A) What is the position (in m) of an image of the Sun at Earth's surface formed by a concave spherical mirror with a radius of curvature of magnitude 7.09 m? (Give your answers with respect to the mirror. B) What is the diameter (in cm) of an image of the Sun at Earth's surface formed by a concave spherical mirror with a radius of curvature of magnitude 7.09 m?

Chapter 34, Problem 041 A lens is made of a transparent material having an index of refraction of 1.70. One side of the lens is flat, and the other convex with a radius of curvature of 27.0 cm. (a) Find the focal length of the lens. (b) If an object is placed 51.0 cm in front of the lens, where will the image be located? (a) Number Units (b) Number Units

A transparent photographic slide is placed in front of a converging lens with a focal length of 2.20 cm. An image of the slide is formed 14.5 cm from the slide. (a) How far is the lens from the slide if the image is real? (b) How far is the lens from the slide if the image is virtual? Step 1 (a) The real image case is shown in the ray diagram. or Object 1 Figure 1 + P 14.5 cm P Notice that here p + q = 14.5 cm, or q = 14.5 cm - p. The thin-lens equation, with focal length f = 2.20 cm, gives 1 - p² (14.5 cm)p+ p+q = F Description Image | cm² = 0. Using the quadratic formula to solve the above equation gives two solutions. The smaller solution is p= cm and the larger solution is p = cm cm. Both are valid solutions for the real image case.

Chapter 34, Problem 011 Spherical mirrors. Object O stands on the central axis of a spherical mirror. For this situation object distance is ps = +12 cm, the type of mirror is convex, and then the distance between the focal point and the mirror is 15 cm (without proper sign). Find (a) the radius of curvature r (including sign), (b) the image distance i, and (c) the lateral magnification m. Also, determine whether the image is (d) real or virtual, (e) inverted from object O or noninverted, and (f) on the same side of the mirror as O or on the opposite side. (a) Number Units (b) Number Units (c) Number Units (p) (e) (f)

A real object is 65 cm from a concave mirror. Find the radius of curvature of the mirror, knowing that (a) the image is real and reduced by 49%, (b) the image is real and magnified by 28%; (b) the image is virtual and enlarged by 78%.

Ch 25, Problem 24 A concave mirror ( f = 36 cm) produces an image whose distance from the mirror is one-third the object distance. Determine (a) the object distance and (b) the (positive) image distance.
