All about the electromagnetic spectrum
| Question | Answer |
|---|---|
| ROYGBIV | Colors of visible light |
| Longest electromagnetic wave; contains television, am, fm, and cell phone frequencies. | Radio waves |
| Type of light given off by heat; Predator vision | Infrared light |
| Type of light that causes sunburn | Ultraviolet light |
| Highest frequency electromagnetic wave. | Gamma rays |
| Powerful enough to see through skin, but bounces off bones. | X-rays |
| Type of electromagnetic wave used to cook food and send radar. | Microwaves |
| Cells in your eye that detect color. | Cones |
| Cells in your eye that detect black and white. | Rods |
| Convex lens | Focuses incoming light |
| Shape of the type of lens in your eye | Convex |
| Shape of lens in glasses of people who can't see far away. | Concave |
| Concave lens | Spreads out incoming light |
| Layer in the eye that contains rods and cones | Retina |
| To bend light | Refract |
| To bounce light off an object | Reflect |
| Speed at which electromagnetic waves travel | 186,000 miles per second |
| Mass-less particles that carry energy on electromagnetic waves | photons |
| Electromagnetic waves do not need this to get from one place to another | Medium |
| The angle at which light comes into a surface before bouncing off. | Angle of Incidence |
| The angle at which light bounces off an object. | Angle of Reflection |
| Part of the retina with no rods or cones where your optic nerve leaves the eye. | Blind Spot |
| In bright light, your pupil does this... | Pupil gets smaller |
| In low light, your pupil does this... | Pupil gets larger |
| If you had alternating panels of yellow and blue on a color wheel, what color would you expect to get. | Green |
| All the colors of the spectrum combined form what color. | White |
| The angle of reflection and the angle of incidence on a flat surface are... | The same angle |
| This part of the eye is like a window that light shines through. | Cornea |
| This is the colored part of your eye. | Iris |
| People who are nearsighted have this problem with their vision. | Lens focuses light too early on the retina |
| People who are farsighted have this problem with their vision. | Lens does not focus light onto the retina - the light is too spread out when it hits the retina |
| For 3-D to work, you need this | Separate images for each eye |
