Classical Gryphons
100
This the material through which a wave travels.
What is a medium?
100
This is the term for the maximum displacement of the medium from its rest position
What is Amplitude?
100

This is the relationship between the frequencyvibrating source creating the wave and the frequency of the wave itself?

It is Equal

100

A point on a standing wave that has no displacement from the rest position.

Node

100
These type of waves are transverse waves consisting of changing electrical fields and magnetic fields.
What are "Electromagnetic Waves"?
200
These are the names for: A. the sort of wave that causes the medium to vibrate at right angles to the direction the wave travels. B. The sort of wave that travels along a surface separating two media C.The sort of wave that causes the medium to vibrate in the same (or opposite) direction that the wave travels?
What are the three types of mechanical waves? A. Transverse Waves B. Surface Waves C. Longitudinal Waves
200
This term refers to the is the number of complete cycles in a given time.
What is the **frequency*** of a wave?
200

This is the relationship between frequency and wavelength.

What is "inversely proportional"?  As frequency goes up wavelength goes down and vice versa

200

The point on a standing wave that has maximum displacement from the rest position.

Antinode

200
This is a region of space that exerts electric forces on charged particles.
What is an "Electric Field"?
300
These are the names for the highest point above the rest position and the lowest point below the rest position of a wave.
What are crests and troughs?
300
This unit of measurement is used to describe a wave's frequency, and it represents the number of cycles per second.
What are Hertz?
300

What happens when a wave with a 3m Crest meets a wave with a 3m Trough?

Complete Destructive Interference... No wave.

this is the technology that noise canceling headphones use

300

These two terms refer to when waves combine to produce a wave with either a larger a larger or a smaller displacement.

What are constructive interference and destructive interference?

300
- Magnetic Field - A region of space that produces magnetic magnetic forces.
What is a " Magnetic Field"?
400
These two terms refer to the areas of waves where the particles in the medium are spaced close together and where they are spread out.
What are compressions and rarefactions?
400
This is the term for any motion that occurs in regular intervals of time.
What is periodic motion?
400

This is the term for what happens when a waves crest meets another waves crest 

Constructive Interference

400
This is the term for a wave that appears to stay in one place and doesn't seem to move through a medium.
What is "standing wave"?
400
These two terms refer to a. The emission of electrons from a metal caused by light striking the metal. b. Packets of electromagnetic energy.
What are a. the "Photoelectric Effect", and b. "Photons?"
500

This is how a wave is created.

source of energy causes a vibration to move through a medium

500

This is the term for the TIME required for one cycle, a complete motion that returns to its starting point.

What is a period?

500
The term when a wave crest meets another waves trough

Destructive Interference

500

This word beginning with the letter N is a point on a standing wave that has no displacement from the rest position.

What is a "node"?
