Which of the following correctly describes the image produced by a plane mirror?

• The image is real and upright.

• $2\ \frac{1}{4}$ meters

• $4\ \frac{1}{2}$ meters

We have our first experience with rear-view mirrors when first learning to drive. Which of the following statements most accurately describes rear-view mirrors?

• Rear-view mirrors are converging such that images appear closer than their actual distance.

• Rear-view mirrors are diverging such that the image produced is virtual, upright, and enlarged.

• Rear-view mirrors are converging such that the image produced is real, upright, and reduced

• Rear-view mirrors are diverging such that the object distance is greater than the image distance.

Which of the following would be an example of using a convex mirror effectively?

• Satellite dishes for collecting radio waves

• Otoscopic mirror for concentrating light

• Dental mirror for closer examination

• Security mirror in store to increase range of view

Which of the following statements correctly identifies a rule for drawing ray diagrams with mirrors?

• A ray incident along the radius vector is reflected back on itself.

• A light ray parallel to the principal axis of the mirror is reflected so that it appears to come from the radius of curvature.

• A light ray pointed directly at the focal point is reflected such that the angle of incidence is equal to the angle of reflection.

Anuja wants to design a solar cooker that will focus sunlight at one spot to generate heat for cooking.

Which of the following mirrors should Anuja use in the solar cooker?

Note: The smooth side is the reflecting part of the mirror, and the dotted side is the back.
