Ray Diagrams & Images
Construct ray diagrams to show the formation of images by plane mirrors and converging lenses, identifying whether images are real or virtual, magnified or diminished, upright or inverted
Suggested ages 12–13
Evidence of understanding
- Draws an accurate ray diagram for a plane mirror showing a virtual, upright, same-size image
- Draws a ray diagram for a converging lens to show image formation
- Uses a ray diagram to determine whether the image is real or virtual and which side of the lens it forms
- Applies ray diagram knowledge to explain how glasses, cameras, or projectors work
Assessment prompt
If Ray Diagrams & Images was asked to show on a diagram where their reflection appears to be when they look in a mirror, could they draw the correct ray paths and explain whether the image is real or virtual — and where it actually appears to be located?
