Reflections and Mirrors

The distance from the vertex of the mirror to the center of curvature is also known as the

• focal length.

• radius of curvature.

• object distance.

• image distance.

The image formed by this converging mirror is

• upright, same size, virtual.

• inverted, same size, real.

• upright, larger, virtual.

• inverted, smaller, real.

• no image is formed.

In the diagram shown, the student stands at location B, 2meters in front of a plane mirror. At which location does the student's image appear to be?

• A
• B
• C
• D

The diagram represents a light ray reflecting from a plane mirror. The angle of reflection for the light is.....

• 25^o
• 35^o
• 50^o
• 65^o

The diagram shows a concave mirror. If the focal length of the mirror is 0.10m, what is its radius of curvature?

• 0.30m
• 0.20m
• 0.10m
• 0.05m

The image formed in a flat mirror is

• larger than the object and farther away.

• reduced and closer to the mirror.

• a real image of the object.

• equal to the height and distance of the object.

What kind of mirror is shown here?

• plane
• concave
• convex
• diffuse

A ray of light is incident on a plane mirror and the angle of reflection is 50 degrees. What is the angle between the incident ray and the reflected ray?

• A. 50 degrees
• B. 25 degrees
• C. 90 degrees
• D. 100 degrees

A real image having a size of 10 cm is formed by a concave mirror. The size of the object is 5 cm.The magnification of the object is

• -2

A concave mirror with a focal length of 30 centimeters is used to examine 0.5 cm wide freckle on a person's face. The person's face is located 15 cm from the mirror. What is the width of the image of the freckle?

• 2.0 cm

• 1.0 cm

• 0.50 cm

• 1.5 cm
