Homework Answers

Answer #1

12) Let the image distance is v.

The object distance u=17 cm.

The focal length f=10 cm.

From the mirror formula

  

  

  

  

The image distance is -6.296296296 cm or -6.3 cm approximately.

14)

An object that is located at the center of curvature of a spherical concave mirror produces A real, inverted image.
