Question

INTERIO There are five problems with parts. Each must be solved on a separate sheet. Always show the units for your answer. c=3x108 m/s 1/(4pi epsilon0)=9x109 Nm2/C2 mu(/(4pi)=10-7 Wb/Am 1.(45pts) I. A convex mirror of radius R = 24 cm is located a distance 36 cm from a converging lens of focal length 10 cm. An object 3 cm high is placed at a distance 15 cm from the vertex of the lens as shown in the diagram. 3) Where is the optical image of the object due to the converging lens? Carefully draw two rays which locate this image." by Using the image in part a) as the object for the mirror, find the position of the image due to the mirror. Carefully draw two rays which locate this image. c) What is the magnification of the system? R=24cm d) is the final image real or virtual and how can you tell? f=10m 3cm O ro 15 10 25 30 35 40 45 60 65 II. we obtained the index of refraction n of glass by observing the critical angle for total internal reflection from a semi-circular piece of glass. a) Obtain the value of n if (at the critical angle) the path of the light ray is as shown in the figure. 6) What is the speed of light in this piece of glass? 37° glass m 2.(35pts) 1. A loud speaker high up on a pole is radiating 100 watts of audio power from directions

Answer 1
