What is the speed of light?
What is 300,000 km/s.
100
Red, Violet, Green, Yellow, etc. are all colors that are part of the _________ ______________ of light on the electromagnetic spectrum.
What is the Visible Spectrum of Light.
100
What is a reference frame? why is this important when talking about relativity?
What is a particular perspective employed by the observer to describe and/or observe motion effectively. Determining relativity is dependent on reference frames.

Can you apply the principle of E=mc2 to nuclear energy? To thermal energy?
What is yes. you can apply this to all energy.
200
Waves transfer energy but not _______.
What is matter.
200
Who discovered the constant for the speed of light?
Who is James Maxwell.
200
Different colors reflect differences in their __________.
What is their frequency (Hz).

If Mort in on the earth and Velma is in the transparent space-craft and they are both holding identical twin cats. What does Velma's cat look like to Mort?
What is smaller, slower, etc.

How can you increase the mass of a cup of water, without adding more water?
What is heat it up.
300
What type of waves are radio waves?
What are sound waves.
300
We know that light does not require a medium, however, what kind of field does light create a disturbance in?
What is an electromagnetic field.
300
On this chart label ultra violet waves. What is their frequency?
What is ultra violet waves are right above the visible spectrum of light and have a frequency ranging from 10 to the 15th - 10 to the 18th.
300
While riding on a very smooth directly west-bound train, would I be able to tell I am in motion with out referencing the outside world? Why or why not?
What is no. because of the principle of relativity. My reference frame doesn't include anything not moving at the same constant acceleration.
300
You electrically charge ballon by rubbing it on your head, then you shake in back and forth. When you do this what happens (that we can not see)?
What is you would create and electromagnetic wave.
400
Why can't we see electromagnetic waves?
What is because the medium for electromagnetic waves are non-material electromagnetic fields.
400
The sun gives off light and therefore energy. What kind is the energy transformation that occurs when the sun warms up your skin?
What is Radiant -> Thermal.
400
What type of wave has the highest frequency? the lowest?
What are Gamma Rays (highest) and Radio Waves (lowest).
400
If Velma and Mort have twin cats and identical meter sticks and Velma is flying at high speeds in a transparent space craft and Mort (on earth) asks Velma to measure her cat so that they get same measurement, how could Velma do this? Can she? why or why not?
What is yes Velma can. She just needs to measure the cat perpendicular to the direction of motion. X and Y are independent.
400
If an object is accelerated close to the speed of light, what will happen to its mass?
What is the mass will increase.
500
On the board, draw and label the two types of wave interference.
What are destructive and constructive.
500
Can we propel a soccer ball to the speed of light? Why or why not?
What is no. we do not have control of enough energy to propel a mass to the speed of light. It would gain infinite mass accelerating to such high speeds.
500
What is infrared radiation? explain.
What is random thermal motion of molecules due to their thermal energy. EX) Night-vision devices... they use heat to detect objects.
500
Velma's normal ball throwing speed in 20m/s. She is in a train moving eastward at 70m/s and throws a ball toward the rear of the train. What is the speed and the direction of the ball relative to Velma? What about relative to Mort standing at the train station the train passed by?
What is 20m/s westward to Velma and 50m/s westward to Mort.
500
What happens to energy during nuclear fission?
What is the total amount of energy is conserved, while the rest mass is not.
