1. Concave, Convex, and Plane Mirrors
By: Marci, Tyler, and John

2. Concave Mirrors A concave mirror is a mirror that is curved inward
Concave mirrors can form real images that are projected out in front of the mirror at the place where the light focuses
Concave mirrors are the only mirrors that can produce both real and virtual images

3. Convex Mirrors
Described as a portion of a sphere that has been sliced away.
Has an outward curvature.
Also referred to as a diverging mirror.

4. Convex Mirrors
Convex mirrors produce VIRTUAL images that are located somewhere behind the mirror.
It is considered a virtual image because light does not actually pass through the image location. It only appears that was due to reflecting light diverging from this virtual image location.

5. Virtual Images
An image formed when outgoing rays from a point on an object always diverge.
The image appears to be at the point of divergence.
Because the rays never converge the image cannot be projected onto a screen.

6. Plane Mirrors These are the mirrors we use on a daily basis
Images are reversed from front to back instead of left to right
Essentially - the object and image for a plane mirror lie on opposite sides, but at the same distance from the mirror
The image is virtual, but the size and object are the same.

7. Overview of the Different Mirrors
Concave Mirrors: curved inward (like a cave)
Convex Mirrors: curved outward
Plane Mirrors: flat, no curvature

8. Real Images
Real images occur when objects are placed outside the focal length of a converging lens or outside the focal length of a converging mirror.
The intersection of the two rays gives the position of the image.
The position of the image can be found through the equation:

9. Differences between the Images
Real images are those where light actually converges, whereas virtual images are locations from where light appears to have converged.
