100

These are all the parts of an electromagnet.

What are batteries, conductive wires, and a ferromagnetic core?

100

The measurement of energy in a wave.

What is amplitude?

100

This is what happens to light when it hits a clear or transparent object; it passes right through!

What is transmission?

100

These are the primary colors of light.

What are Red Blue and Green?

200

This is the term for a coil of wire that produces a magnetic field.

What is a solenoid?

200

This type of wave doesn't need a medium to travel, so it can move through space.

What is an EM (electromagnetic) wave?

200

These two light interactions are responsible for our eyes seeing different objects as different colors. Some light makes it to our eyes, the rest disappears.

What are reflection and absorption?

200

This is the color we see when all waves of color are present.

What is white light?

300

In the Right-Hand rule, this part of your hand shows the direction of the magnetic field around a wire.

What are your curled fingers?

300

These two properties of waves can be multiplied to measure a wave's speed. They're also responsible for different colors of light, and different pitches of sound.

What are wavelength and frequency?

300

This is the type of energy that light turns into when it is absorbed into an object. 

What is heat energy?

300

A rainbow contains all colors of light, which are organized by what wave property?

What is wavelength/frequency?

400

This type of metal is found at the earth's core. It's the reason why the earth has a magnetic field, and the best type of metal to use in an electromagnet core.

What is iron?
400
A wave with a very short wavelength will have this magnitude of frequency. This is because the speed of light needs to remain constant, so wl and f must change to balance each other out.

What is a high frequency?

400

Light must enter a medium at an angle in order to see this interaction occurring. The angle causes the light wave to change speeds and bend.

What is refraction?

400

These colors are absorbed by yellow objects, allowing what's left of the visible spectrum to reflect and hit our eyes.

What are RO GBIV?
