A person with colorblindness is unable to see color the same as most people. Which part of the human eye is most likely damaged?
Match the structure of the eye with its correct function.
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Iris | arrow_right_alt | Layer at the back of the eye containing light-sensitive cells (rods and cones) that convert light into electrical signals. |
Retina | arrow_right_alt | Transmits electrical signals from the retina to the brain, where they are processed as images |
Lens | arrow_right_alt | Colored part of the eye that is a muscle. Controls the size of the pupil, adjusting light intake. |
Optical Nerve | arrow_right_alt | Transparent structure behind the pupil that focuses light onto the retina. |

A piece of frosted glass cannot be seen through clearly. Figure 1 shows an image of the frosted glass.
Draw arrows to show the path of light when it hits the surface of the translucent glass.
You may draw up to 4 arrows
Figure 2 shows the same surface of frosted glass. A piece of clear packing tape has been added to the surface. When a piece of clear packing tape is put on the surface, it become transparent.
Draw arrows to show the path of light when it hits the surface of the transparent glass.
You may draw up to 4 arrows
