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: 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 Type: real or virtual
