Exam 34: Images

A convex spherical surface with radius r separates a medium with index of refraction 2 from air. As an object in air is moved toward the surface from far away along the central axis, its image:

The passenger-side rear view mirror on a car says, "Objects in the mirror may be closer than they appear". Assuming the images are not inverted, this mirror must be:

The object-lens distance for a certain converging lens is 400 mm. The image is three times the size of the object. To make the image five times the size of the object, the object-lens distance must be changed to:

In a two lens microscope, the intermediate image is:

An object is in front of a converging lens, at a distance less than the focal length from the lens. Its image is:

An erect object is in front of a convex mirror a distance greater than the focal length. The image is:

A camera with a lens of focal length 6.0 cm takes a picture of a 1.4-m man standing 11 m away. The height of the image is about:

A hollow lens is made of thin glass as shown. It can be filled with air, water (n = 1.3) or CS₂ (carbon disulfide, n = 1.6). A beam of parallel light entering the lens will diverge if the lens is filled with:

An object is 20 cm to the left of a lens of focal length +10 cm. A second lens, of focal length +12.5 cm, is 30 cm to the right of the first lens. The distance between the original object and the final image is:

An ordinary magnifying glass in front of an erect object produces an image that is:

As an object is moved from the center of curvature of a concave mirror toward its focal point its image:

Roadway mirages are formed when:

When you stand in front of a plane mirror, your image is:

An erect object is located on the central axis of a spherical mirror. The magnification is -3. This means its image is:

A concave spherical mirror has a focal length of 12 cm. If an object is placed 6 cm in front of it the image position is:

A concave refracting surface is one with a center of curvature:

Two plane mirrors make an angle of 120 $\degree$ with each other. The maximum number of images of an object placed between them is:

Which type(s) of lenses can produce both real and virtual images?

If the image distance is negative,

A concave refracting surface of a medium with index of refraction n produces a real image no matter where an object is placed outside:
