Document Summary

34 (continued: spherical mirror (sections 34-4 & 34-5) -> radius of curvature (r), focus and focal length (f) Mirror equation: [ 1/p + 1/q = 1/f ] Example: the same as the previous example, except the object is placed 7. 5 cm to the left of the mirror. Mirror equation [ 1/p + 1/q = 1/f ] Example: an object 0. 4 cm tall is placed 15 cm to the left of the vertex of a convex mirror having a radius of curvature of 20 cm. Find the image using both the graphical method and mirror equation. *** make changes: problem 34-25 change m, m must be (- 0. 4). Problem 34-29 change r and i. r must be (- 40 cm), i (or q) must be (- 4 cm). *** answers to additional problem (see oct. 22 lecture outline: calculate the resistance of transmission wires: 0. 05 ohm/km x 14 km = 0. 7 ohm.
