100

A wave that consists of electric and magnetic fields that vibrate at right angles.

Electromagnetic wave

100

This interaction of light explains why you can see things that do not produce their own light. 

Reflection

100

What is the electromagnetic spectrum?

all the frequencies or wavelengths of electromagnetic radiation.

100
Give an example of a naturally occuring pigment

Chlorophyll, Anthocyanin, Xenophyll, Cyan

100

What is the largest ocean?

Pacific

200

A change in the direction of a wave when the wave finds an obstacle.

Diffraction

200

Even though the planet mars does not emit light, why can we still see it in the night sky?

light from the sun reflects off of it.

200
What kind of waves are used for communication?

Radio waves

200

In your own words, explain how color is perceived by the human eye

Color is a result of the reflection of light at a certain wavelength. The rest of the colors associated with the visible spectrum are absorbed. 

200

Largest mammal?

Blue whale

In order: 

Can't see through it

Kind of see through

See through it

300

What three colors can be percieved?

Red, green and blue.

300

These rays are a result of the decay of atomic nuclei

Gamma Rays

300

Explain the color theory using red, green and blue and how it produces different colors

Colors outside of red, green and blue are a combination or an absence of the colors

300

The state flower of NH

Purple Lilac
400

The passing of light or other form of energy through matter

transmission

400
What interaction of light is responsible for the color of the sky?

scattering of blue light.

400

What waves have been shown to appear as background radiation for the universe?

microwaves

400

What part of the brain is responsible for vision?

Occipital lobe (back of the head)

400

What do we call a rapidly rotating neutron star?

Pulsar

500
A substance that gives another substance or material color.

pigment

500
What are electromagnetic waves made of? (each team only gets 1 guess)

a.) Vibrating particles

b.) Vibrating charged particles

c.) Vibrating electrical and magnetic fields

d.) all of the above

c

500

List the EMS in order.

Radio, micro, infrared, visible light, UV, XRay, Gamma

500

Explain why leaves change color in the fall.

Leaves typically contain chlorophyll, a green pigment that plants begin to produce less in Autumn as a result of the change in the photoperiod. This leads to smaller molecules being made that reflect the red, orange and ochre tones.

What insect can lift 50x its own weight?

Ants
