Qualitative Characteristics of Images

Which kind of curved mirror bulges its reflective surface toward the light?

• Concave

• Convex

• Plane

• All of these

A concave mirror is a curved mirror in which the reflective surface bulges away from the light source.  Why is it also known as a converging mirror?

• Parallel incident rays diverge after reflection.

• Parallel incident rays diverge in one direction.

• Parallel rays converge at the focus after reflection.

• Parallel incident rays converge in any direction after reflection.

Which of the following differentiates a converging mirror from a diverging mirror?

• Diverging mirror is used to focus light while a converging mirror is not used to focus light.

• Diverging mirror reflects light inward to one focal point. It is used to focus light while the converging mirror reflects light outwards.

• Converging mirror bulges towards the light source while in a diverging mirror, the reflecting surface is recessed inward.

• Converging mirror reflects light inward to one focal point. It is used to focus light while the diverging mirror reflects light outwards.

Which of the following illustrates a converging mirror?

• I

• II

• III

• IV

An object is placed at the focal point of a concave mirror. Where is the location of the image formed?

• Between C and F 

• Between F and V

• In front of the mirror

• No image is formed

An object is located at the center of the curvature of a concave mirror. What is the orientation and location of the image?

• Inverted at C 

• Inverted at F

• Upright at C

• Upright between C and F

How would you describe the image in the given diagram?

• inverted, real, same, located between C and F

• inverted, real, reduced, and located between C and F

• upright, virtual, enlarged, located between C and F

• upright, virtual, reduced, located between C and F

When a small object is placed on the principal axis of a concave mirror between the focus and the mirror (as in the figure below), the image formed is ____________.

• erect, reduced, and real

• erect, magnified, and virtual

• inverted, magnified, and real

• inverted, reduced, and real

What type of lens produces an image that is always upright, reduced, and virtual?

• Concave

•  Convex

• Both a & b

• None of these

How would you compare the image formed by the concave and convex lens?

• Concave lens produces virtual and upright image while convex lens real and inverted image.

• Concave lens produces a real and upright image while convex lens produces a virtual and inverted image.

• Concave lens produces a virtual and enlarged image while convex lens produces a real and reduced image.

• None of these
