Name:__________________________ Period:__________

1. A 4.00-cm tall light bulb is placed a distance of 45.7 cm from a concave mirror having a focal length of 15.2 cm. Determine the image distance and the image size.

2. Determine the image distance and image height for a 5.00-cm tall object placed 45.0 cm from a concave mirror having a focal length of 15.0 cm.

3. Determine the image distance and image height for a 5.00-cm tall object placed 20.0 cm from a concave mirror having a focal length of 15.0 cm.

4. A magnified, inverted image is located a distance of 32.0 cm from a concave mirror with a focal length of 12.0 cm. Determine the object distance and tell whether the image is real or virtual.

5. A concave spherical mirror has a focal length of 10.0 cm. Locate the image when an object is placed upright 30cm from the mirror. Find the magnification of the image.

6. A concave makeup mirror is designed so that a person 25cm in from of it sees an upright image at a distance of 50cm behind the mirror. What is the radius of curvature of the mirror? What is the magnification of the image? Is the image real of virtual.

7. A pen placed 11cm from a concave mirror produces a real image 13.2 cm from the mirror. What is the focal length of the mirror? What is the magnification of the image? If the pen is placed 27cm from the mirror, what is the new position of the image? Describe the image as real/virtual, upright/inverted and image magnification.

8. A spherical glass ornament is 6cm in diameter. If an object is places 10.5cm away from the ornament, where will its image form? Describe the image as real/virtual, upright/inverted and image magnification.

9. A soda bottle is placed 44cm from a convex mirror. If the focal length is 33cm, how far from the mirror’s surface does the bottle’s image form? Describe...
