List the parts of the EM Spectrum in order starting with Radio Waves | Radio, Microwave, Infrared, Visible Light, Uv Rays, X-Ray, Gamma Ray |
Which part of the Spectrum has the shortest wavelength | Gamma Rays |
Which part of the Spectrum has the lowest frequency | Radio Waves |
As you move from Gamma back to Radio waves what happens to wavelength | It gets longer |
As you move from Radio to Gamma what happens to frequency | It gets faster/higher |
Which two parts of the spectrum deal with communication and signals | Radio Waves and Microwaves |
This part of the spectrum can cause skin damage and can sterilize | UV Rays |
This part of the spectrum allows you to see inside. | X-Rays |
Infrared Rays deal with __________. | HEAT |
The most penetrating of all used in medicine and can also be neclear | Gamma Rays |
When visible light is refracted through a prism we see different colors because each color has a different _____________. | Wavelength |
All the colors of the rainbow put together created what type of light | WHITE LIGHT |
How do we see colored objects | Light strikes them and the color you see if reflected and all the rest are absorbed |
How do we see white objects | Light strikes them and all colors are reflected |
How do we see black objects | Light strikes them and no colors are reflected, they are all absorbed |
What are the three types of materials that light can interact with | Transparent, Translucent and Opaque Materials |
What happens when light strikes an opaque material | No light passes through, it is either reflected or absorbed |
What happens when light strikes a transparent material | All light passes through |
What happens when light strikes a translucent material | Some light passes through but not all; light is scattered |
When light strikes an object it can either be _________, _________ or ______. | Reflected, Absorbed or Transmitted |
What are the 6 main parts of the eye that process light | Cornea, Iris, Pupil, Lens, Retina, Optic Nerve |
Which two parts of the eye bend light as it passes through | The cornea and the lens |
What is the difference between the iris and the pupil | The iris is the colored part that controls how much light enters; the pupil is the black hole in the eye |
What is the job of the optic nerve | To process and send signals of light to the brain |
The retinal is a wall of cells (like a screen) that has rods and cones. What do the rods and cones do | The rods distinguish shades (black, white and gray) while the cones distinguish color |
