Light Energy
This is a form of wave energy that is constantly moving through the universe and that travels in a straight line.
What is light?
This is what we call the different colors of light that we can see.
What is the Visible Spectrum?
There are different color models, but all of them use these three.
What are primary colors?
This is any surface that can reflect light to form an image, or picture, of an object.
What is a mirror?
This arrangement orders electromagnetic waves in the order of the wavelengths.
What is the electromagnetic spectrum?
These waves move perpendicular to the way that the matter is moving. Light is an example of this type of wave.
What are transverse waves?
This is the way light generally travels.
What is in a straight line?
These colors cannot be made from any other color. God made our eyes and brains so that they combine these colors into all the other colors we see.
What are primary colors?
This type of mirror curves inward. In it, images are magnified and appear larger.
What is a concave mirror?
This type of wave has the longest wavelength.
What is a radio wave?
This is the distance between 2 crests or 2 troughs.
What is wavelength?
This is the bending of light as it passes from one medium into another.
What is refraction?
These are the opposites of the primary colors.
What are complementary colors?
This type of mirror curves outward. In it images appear smaller.
What is a convex mirror?
This type of wave has the shortest wavelength.
This is the height of a wave.
What is amplitude?
This happens when light bounces off an object.
What is reflection?
These are the complementary colors.
What are magenta, cyan, and yellow?
This is a pieces of glass or other transparent object that refracts light and produces an image.
What is a lens?
Heat is produced by this type of wave.
What is an infrared wave?
This is the measure of the number of waves that pass a certain point in one second.
And
This is the distance one wave travels in one second.
What is frequency?
And
What is speed?
This bends light to show the color spectrum.
What is a prism?
These are opaque substances used to color other materials.
What are pigments?
This type of telescope uses a concave mirror to gather and focus light.
What is a reflecting telescope?
Other than gamma, these types of waves have a higher frequency than visible light.
What are ultraviolet, and x-ray?
This is the math equation for speed.
What is wavelength x frequency = speed?
These are the three types of matter through which light either passes or is absorbed.
What are transparent, translucent, and opaque matter?
These are the primary colors of pigments.
What are magenta, cyan, and yellow?
A refracting telescope usually uses two lenses to serve these two purposes.
What are gathering light and magnifying the image?
These types of rays are why you can still become sunburned on a cloudy day.
What are ultraviolet rays?
What is the primary difference between electromagnetic waves and mechanical waves?
Electromagnetic waves can travel through empty space. Mechanical waves can only move through matter.
Why do lemons appear yellow to us?
Because the lemon is absorbing all colors other than yellow. Yellow it is reflecting.
If you were to look at colors on a piece of printed paper under a microscope, what would you see?
Tiny dots of colors - usually four-colors (yellow, magenta, cyan, and black).
Explain the relationship between light and mirrors, especially focusing on the type of surface that is used for a mirror.
Light reflects in a straight line. When bouncing off a smooth surface, the image it produces will usually look exactly like what is being reflected. When a mirror has a rough surface, the image reflected will be distorted because the light is bouncing in different directions.
Describe the 5 properties of waves.
Crest (highest point), Trough (lowest point), Rest position, Aptitude (distance from the rest position to the crest or trough), and Wavelength (distance between crests or troughs).
