The mirror above has a radius of curvature $r = 10$ cm. A candle is placed at $s = 20$ cm as shown. Find:

• The focal length of the mirror (draw the focal point in on the diagram above).
• The location $s'$ of the image in centimeters.
• The magnification of the image.
• State whether the image is real or virtual, erect or inverted.
• Draw the ray diagram for this arrangement using the three ``named'' rays used for both lenses and mirrors as shown in class. Obviously it should validate your answers to the above.
