Colors of Light
This color of light has the longest wavelength and is the first color in the rainbow.
What is red?
This kind of energy comes from the sun’s rays.
What is solar energy?
This everyday object shows your reflection when you look into it.
What is a mirror?
When a straw looks “bent” in a glass of water, it’s because of this.
What is refraction?
This is the biggest and most important source of light for Earth.
What is the sun?
When you mix red and blue pigment, the color you get is this.
What is purple?
Turning the blades of a wind turbine creates this kind of energy.
What is wind energy?
A mirror that curves inward, like the inside of a bowl, is called this.
What is a concave mirror?
A clear object shaped to bend light, like in glasses or a magnifying glass, is called this.
What is a lens?
Fire, lightning, and the sun are examples of these.
What are natural light sources
When all the colors of light are combined, they make this color.
What is white?

Some living things, like jellyfish and fireflies, can glow in the dark because of this process.
What is bioluminescence?
This type of light is just beyond the visible spectrum and can cause sunburns.
What is ultraviolet (UV)?
This type of energy is carried by light waves and lets us see.
What is radiant energy (or light energy)?
A mirror that curves outward, like the back of a spoon, is called this.

What is blue?
Splitting atoms inside a power plant releases this powerful type of energy.
What is nuclear energy?
This tool uses mirrors inside so you can see over a wall or around a corner.
What is a periscope?
A lens that curves inward and spreads light rays apart is called this.
What is a concave lens?
The sun produces light because atoms inside it undergo this process.
What is fusion (nuclear fusion)?
