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
Electromagnetic Spectrum (Parts)
#1 Which two parts of the spectrum deal with communication and signals Radio Waves and Microwaves
#2 This part of the spectrum can cause skin damage and can sterilize UV Rays
#3 This part of the spectrum allows you to see inside. X-Rays
#4 Infrared Rays deal with __________. HEAT
#5 The most penetrating of all used in medicine and can also be neclear Gamma Rays
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
Final Question
Why is the sky blue Blue light is scattered more than any other color
