As the period of a standing wave increases, the frequency does this.
What is decreases?

I always travel in the direction of the electric field.
What is a proton?

On a television screen, these are the two colors that are mixed together to produce yellow on the screen.
What is red and green?
100
This is also called a beta particle.
What is an electron?
100
This force governs the movement of planets and stars in space.
What is gravity?
200
This is the position of maximum amplitude in a standing wave.
What is an anti-node?
200
Outside a magnet, magnetic field lines are drawn in this direction.
What is north to south?
200
I am the smallest part of the electromagnetic spectrum.
What is visible light?
200
I warm the earth from the outside.
What is nuclear fusion?
200
This force is mostly responsible for chemical reactions.
What is the electromagnetic force?
300
When astronomers look at light from distant galaxies, they observe a red shifting of the light. They conclude that the galaxies are moving in this direction.
What is away from us?
300
Below a certain temperature, I exhibit zero electrical resistance.
What is a superconductor?
300
I am the color the sun appears when viewed from the surface of the moon.
What is yellow-white?
300
They are emitted by de-excitation of the atomic nucleus.
What are gamma rays (particles)?
300
Name the four fundamental forces.
What is gravity, electromagnetic, strong (nuclear), and weak?
400
These are the three variables that natural frequency depends on.
What are size, shape, and elasticity?
400
I am the pole of a compass needle that points to the south pole of a magnet.
What is north?
400
I am the color that produces white light when mixed with green.
What is magenta?
400
This is emitted when an isotope decays and forms a new isotope with an atomic number minus two and an atomic mass number minus four.
What is an alpha particle (or helium nucleus)?
400
This force is responsible for protons attracting each other when close together in the nucleus.
What is the strong (nuclear) force?
500
Fourier discovered that compound, periodic waves could be represented by them.
What are sine waves?
500
I am the charge on a particle that slows down when released in the presence of an electron.
What is negative?
500
I am the color that a full moon appears through volcanic ashes that scatter red light.
What is cyan?
500
A sample of a particular radioisotope is placed near a Geiger counter which registers 100 counts per minute. Two hours later, the detector counts a rate of 25 counts per minute. This is what the physicist determines that the half-life of the material to be.
What is one hour?
500
I am capable of changing a neutron into a proton, causing nuclear decay.
