This is an example of a _____________ mirror

• Concave
• Convex
• Plane
• Magnifying

This image is.....

• inverted and smaller
• inverted and larger
• not inverted and smaller
• not inverted and larger

The concave spherical mirror of radius r shown above has focal point F and center of curvature C. An object is placed at a distance 2r from the mirror. Where will the image be formed?

• Between C and the object

• To the right of the object

• Between F and the mirror

• To the left of the mirror

• Between F and C

A physics student places an object 6.0 cm from a converging lens of focal length 9.0 cm. What is the magnitude of the magnification of the image produced?

• 0.6

• 2.0

• 3.6

• 3.0

• 1.5

An object is placed in front of a converging thin lens at a distance from the center of the lens equal to half the focal length. Compared to the object, the image is

• upright and smaller

• inverted and smaller

• upright and larger

• inverted and the same size

• inverted and larger

A group of students collected data using a lens. They varied the distance s_o of an object from the lens and measured the image distance s_i. The figure above is their graph of the inverse of the image distance as a function of the inverse of the object distance. The focal length of the lens is approximately

• 2.0 m

• 1.0

• 4.0

• 1.5

Which of the rays shown above is correct for this diverging mirror?

• 1

• 2

• 3

• 4

A student uses a convex lens to create images and collects the data shown above. The focal length of the lens is in which of the following ranges?

• 0–5 cm

• 5-10 cm

• 10-15 cm

• 15-25 cm
