A concave spherical mirror has a radius of curvature of 10.0 cm. Calculate the location and size of the image formed of an 8.00-mm-tall object whose distance from the mirror is (a) 15.0 cm. (b) 10.0 cm. (c) 2.50 cm. and (d) 10.0 m.
6. Repeat the previous problem, except use a convex mirror with the same magnitude of focal length.
24.6. Set Up: To find the location of the image use
Solve: (a) s = 15.0 cm.
y′ = my = +2.00 mm. The image is 3.75 cm behind the mirror. It is 2.00 mm tall and is upright.
(b) s = 10.0 cm.
y′ = my = +2.67 nun. The image is 3.33 cm behind the mirror. It is 2.67 mm tall and is upright.
(c) s = 2.50 cm.
y′ = my = +5.33 nun. The image is 1.67 cm behind the mirror. It is 5.33 mm tall and is upright.
(d) s = 1000 cm.
y′ = my = +0.040 mm. The image is 4.98 cm behind the mirror. It is 0.040 mm tall and is upright.

- A convex mirror with a radius of curvature of 25.0 cm is used to form an image of an arrow that is 10.0 cm away from the mirror. If the arrow is 2.00 cm tall and inverted (pointing below the optical axis), what is the height of the arrows image?arrow_forwardThe disk of the Sun subtends an angle of 0.533 at the Earth. What are (a) the position and (b) the diameter of the solar image formed by a concave spherical mirror with a radius of curvature of magnitude 3.00 m?arrow_forwardA lamp of height S cm is placed 40 cm in front of a converging lens of focal length 20 cm. There is a plane mirror 15 cm behind the lens. Where would you find the image when you look in the mirror?arrow_forward

Assume you place your eye 5.0 cm from the magnifying glass.arrow_forwardWhat is the magnification of a magnifying lens with a focal length of 10 cm if it is held 3.0 cm from the eye and the object is 12 cm from the eye?arrow_forwardThe magnification of an upright image that is 34.0 cm away from its object is 0.400. What type of lens is used to form the image, and what is its focal length?arrow_forward
- What will be the formula for the angular magnification of a convex lens of focal length f if the eye is very close to the lens and the near point is located a distance D from the eye?arrow_forwardA converging lens has a focal length of 10.0 cm. Locate the object if a real image is located at a distance from the lens of (a) 20.0 cm and (b) 50.0 cm. What If?
