Light Properties
What is the bending of light waves called?
Refraction.
What filter color is best at absorbing light?
Black.
What type of material best allows light to pass through? Please include an example of this material.
Transparent = Window, Glasses, Clear Filter, See Through Plastic / Paper.
What is the spectrum of colors that our eyes can see called?
Visible Light Spectrum.
Draw a real life example of a source of light (something that can create light). Bonus points for drawing an example that no other group chose.
Sun, Lightbulb, Flashlight, Fire, Moon, Glowstick, Electronic Screen.
What process occurs when light bounces back from an object?
Reflection.
What filter color would be best at transmitting blue light?
Blue / Transparent / Clear.
What type of material best blocks light from passing through? Please include an example of this material.
Opaque = Wooden Door, Brick Wall, Apple, Any Completely Solid Object.
What color do we see when ALL light from the visible spectrum is reflected and what color do we see when ALL light from the visible spectrum is absorbed?
White & Black.
Draw light rays being reflected by an object. Please include the name of the object in the drawing. Bonus points for using an object that no other group chose.
Flat Mirror, Concave Mirror, Convex Mirror, Water, White Paper, Metal Objects.
What process occurs when light is blocked by an object?
Absorption.
What are the 3 primary colors of light and why are they called primary colors?
Red, Green, Blue.
They can be combined to create almost any color.
What object is best at separating white light into all of it's individual colors? How does this object do this (use a specific light process in your answer)?
Prism. The light is refracted and separates out the individual colors.
What does light act / behave like? Bonus points for both correct answers.
Particles / Photons and Waves.
Wavicles.
Draw light rays being absorbed by an object. Please include the name of the object in the drawing. Bonus points for using an object that no other group chose.
Wood, Coal, Organic Matter, Dark Colored / Black Objects
What process occurs when light passes through an object in a straight line?
Transmission.
What are the 3 secondary colors of light and why are they called secondary colors?
Magenta, Cyan, Yellow.
They are made by mixing 2 primary colors of light.
What type of material allows some light to pass through but also blocks some light? Please include an example of this material.
Translucent = Frosted Glass, Tinted Car Window, Sunglasses, Wax Paper, Vegetable Oil, Tissue, Semi-Transparent Solids / Plastics.
What does each letter in the acronym ROYGBIV stand for? What is a real life example of this?
Red, Orange, Yellow, Green, Blue, Indigo, Violet.
Rainbows / Visible Light Spectrum.
Draw light rays being transmitted by an object. Please include the name of the object in the drawing. Bonus points for using an object that no other group chose.
Window, Glass, Glasses, Clear Filter, See Through Plastic / Paper.
What are the 3 processes that can occur when light hits the surface of an object?
Transmission, Reflection, Absorption.
What color do you create by mixing red and green?
What color do you create by mixing red and blue?
What color do you create by mixing green and blue?
What color do you create by mixing red, green, and blue?
Yellow.
Magenta.
Cyan.
White.
What are at least 3 different factors that will influence how light will react with the surface of an object? Bonus points for naming more than 3 different factors.
The power / intensity of the light.
The color of the light.
The material of the object.
The shape of the object.
The color of the object.
How do the light processes of absorption and reflection relate to what we see as the color of an object?
When visible light hits the surface of an object, some of the color will be absorbed and some of the color will be reflected. We do not see the absorbed color. The reflected color is what we see in our eyes.
Draw light rays being refracted by an object. Please include the name of the object in the drawing. Bonus points for using an object that no other group chose.
Prism, Ice, Glass, Lens, Water.
