Tracing Image Formation in Curved Mirror

Converging Mirror

Concave mirror can be also called as what?

Converging Mirror

A _____ ____ has a concave reflecting surface.

Real Image

The mirror can form _____ when the object is outside the focus, and an inverted image is formed.

Virtual Image

The mirror forms _____ when the object is within the focus, creating an erect image.

No

Is there an object formed when the object is at the focus?

1. Shaving Mirror

2. Make-up Mirror

3. Microscopes

4. Ophthalmoscopes

5. Headlights

6. Solar Furnaces

Some uses of concave mirror:

1. Center of Curvature (C)

2. Focus (F)

3. Vertex (V)

4. Principal Axis

5. Focal Length (f)

6. Radius of Curvature (R)

Curved Mirror Terminologies:

Center of Curvature (C)

the center of the circle, of which the mirror represents a small arc.

Focus (F)

the point where parallel light rays converge and are always found on the inner part of the "circle," in which the mirror is a small arc, and the focus of a mirror is one half of the radius.

Vertex (V)

where the mirror crosses the principal axis.The center of a spherical reflecting surface is called the center of curvature (C).

Principal Axis

line drawn through the vertex, focus, and center of curvature of the mirror on which the object rests.

Focal Length

the distance from the focus to the vertex of the mirror.

Radius of Curvature (R)

the distance from the curvature's center to the mirror's vertex. It corresponds to the radius of the circle.

Convex Mirror

It is also called diverging mirror.

Convex Mirror

such as a fisheye mirror or diverging mirror, is a curved mirror in which the reflective surface bulges towards the light source.

Diverging Mirror

light rays that strike the mirror surface are reflected so that they diverge or "go apart" and never meet at a point.

Convex Mirrors

reflect light outwards; therefore, they are not used to focus light.

2. Magnifying Glass

3. Telescopes

4. Binoculars

5. Hallway safety mirror

Some Uses of Convex Mirror:

1. The focal length is negative when the image is behind the mirror, although the object is placed facing the mirror.

2. The object and the focus are on opposite sides of the mirror. The object faces the mirror, and the focus is behind the mirror.

3. Only virtual images are formed. All images are smaller than the object.
