Electromagnetic Spectrum (General) |
#1 |
List the parts of the EM Spectrum in order starting with Radio Waves |
Radio, Microwave, Infrared, Visible Light, Uv Rays, X-Ray, Gamma Ray |
#2 |
Which part of the Spectrum has the shortest wavelength |
Gamma Rays |
#3 |
Which part of the Spectrum has the lowest frequency |
Radio Waves |
#4 |
As you move from Gamma back to Radio waves what happens to wavelength |
It gets longer |
#5 |
As you move from Radio to Gamma what happens to frequency |
It gets faster/higher |
Visible Light |
#1 |
When visible light is refracted through a prism we see different colors because each color has a different _____________. |
Wavelength |
#2 |
All the colors of the rainbow put together created what type of light |
WHITE LIGHT |
#3 |
How do we see colored objects |
Light strikes them and the color you see if reflected and all the rest are absorbed |
#4 |
How do we see white objects |
Light strikes them and all colors are reflected |
#5 |
How do we see black objects |
Light strikes them and no colors are reflected, they are all absorbed |
How Materials Transmit Light |
#1 |
What are the three types of materials that light can interact with |
Transparent, Translucent and Opaque Materials |
#2 |
What happens when light strikes an opaque material |
No light passes through, it is either reflected or absorbed |
#3 |
What happens when light strikes a transparent material |
All light passes through |
#4 |
What happens when light strikes a translucent material |
Some light passes through but not all; light is scattered |
#5 |
When light strikes an object it can either be _________, _________ or ______. |
Reflected, Absorbed or Transmitted |
The Eye |
#1 |
What are the 6 main parts of the eye that process light |
Cornea, Iris, Pupil, Lens, Retina, Optic Nerve |
#2 |
Which two parts of the eye bend light as it passes through |
The cornea and the lens |
#3 |
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 |
#4 |
What is the job of the optic nerve |
To process and send signals of light to the brain |
#5 |
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 |
