Of the following colors, which has the lowest energy? Blue, Orange, Yellow, or Green

Orange

200

Which color on the EM spectrum has the longest wavelength?

Red

300

Why do we see a firework explode before we hear the boom?

Sound waves travel slower in the air than light waves

300

What medium does a sound wave travel fastest through?

Solids

300

What is the name given to a material in which only SOME light can pass through?

Translucent

300

What colors are being absorbed in a purple shirt?

ALL colors except purple

400
What will happen to the frequency of the waves as the wavelength increases?

Frequency increases

400

If a light wave travels from the sun, through the atmosphere, then through a window, and finally through a fish tank of water. Through which substance did the light wave travel fastest?

The atmosphere

400

For sound waves, if the temperature of the medium decreases, then what happens to the speed of sound?

The speed of sound decreases

400

Electromagnetic waves are created when electricity and magnetism oscillate. What does it mean to oscillate?

To move back and forth

400

Why do white shoes look white?

The reflect ALL the colors of light

500

The distance from the top of a crest of a wave to the bottom of the trough of the wave is _______ the amplitude.

Double

500

Where do light waves travel the fastest? Why?

Outer space, because it is the closest thing to a perfect vacuum. Light waves travel fastest through vacuums/empty space.

500

If an alien in space asks another alien a question, what will their response be?

Nothing, you cannot hear sound in space! This is because outerspace acts as a vacuum.

500

Thinking back to the NASA video, why do we see the sun as yellow?

The temperature. If it was hotter it would look blue. If it was colder it would look red. 

500

How do we see black objects?

No colors of light are being reflected, they are all being absorbed.
