How Light Travels
Light can easily pass through these materials so that images can be seen on the other side. (Example: window)
What is transparent?
The type of electromagnetic radiation that can be used to view inside of bodies and objects.
What is an X-ray?
A 3-dimensional clear glass or plastic shape that refracts white light and separates it into the different colors.
What is a prism?
If you combine the primary colors of light, this is the color you will get.
What is White Light?
Some light can pass through these materials, but images on the other side cannot be seen clearly. (Example: wax paper)
What is translucent?
This type of electromagnetic radiation can be used to cook food quickly.
What are Microwaves?
The 7 colors of the visible light spectrum in order from longest wavelength to shortest wavelength.
What is Red, Orange, Yellow, Green, Indigo, and Violet?
True or False: You can get a sunburn on a cloudy day.
What is True?
No light can pass through these objects, creating a shadow opposite of the light source. (Example: wood)

What is Ultraviolet Light?
The 3 primary colors of light.
What are Red, Green, and Blue?
The bending or spreading of light waves as they pass around an obstacle or through a narrow opening.
What is diffraction?
When light rays bounce off a smooth surface.
What is reflection?
The type of electromagnetic radiation with the shortest wavelength. (Radio, Infrared, or Gamma Ray)
What is a Gamma Ray?
The color you get when you combine blue light with green light.
What is Cyan?
True or False: If you shine a red laser and a violet laser through a prism at the same angle, they are bent the same so the points end up right next to each other.
What is False?
Light rays are bent when when passing from one medium to another.
What is refraction?
This surrounds the Earth and protects us from many forms of electromagnetic radiation.
What is the atmosphere?
The reason we see different colors is because each has a different _______________.
What is a wavelength?
The reason a lime looks green to us.
