1. Real and Virtual Images
SNC2D

2. How does an image form in a plane mirror?
Step 1: A multitude of light rays from the object will be incident towards the mirror.

3. How does an image form in a plane mirror?
Step 2: The light will reflect off the mirror according to the Law of Reflection.

4. How does an image form in a plane mirror?
Step 3: The image is where all the reflected light rays intersect; in this case, it’s behind the mirror.

5. How does an image form in a plane mirror?
i.e. the image is where an observer thinks the light rays originate.

6. Virtual Images
An image formed by the intersection of the extensions of the light rays is called a virtual image. It cannot be focused on a screen.

7. Real Images
An image formed by the intersection of actual light rays is called a real image. It can be focused on a screen.

8. Image Properties For any image, note the image:
Size: if the image is larger, smaller, or the same size as the object

9. Image Properties For any image, note the image:
Size: if the image is larger, smaller, or the same size as the object
Attitude: if the image is upright or inverted (i.e. upside-down)

10. Image Properties For any image, note the image:
Size: if the image is larger, smaller, or the same size as the object
Attitude: if the image is upright or inverted (i.e. upside-down)
Location: where the image is relative to the mirror or lens

11. Image Properties For any image, note the image:
