The name of the famous bridge that collapsed
Tacoma Narrows Bridge
What do we call it when a light beam bounces off a mirror?
Reflection
What does the FCC stand for?
Federal Communications Commission
What is an electromagnetic wave with the most energy and shortest wave length.
gamma ray
What energy did the compression wave transfer?
Motion energy
Identify the problem
Research
Decide and design
Build a prototype

Engineering Cycle
What is the angle of the reflected beam called?
Angle of Reflection
What color is being absorbed by a white shirt?
No colors
Fiber optics
What is the point where the wave crosses the resting line of the spring?
Node
Loudness of a sound wave is measured in?
decibels (dB)
What is a line perpendicular to a surface such as a mirror that forms a 90 degree angle with the surface?
normal line
What do AM and FM stand for?
Amplitude Modulation and Frequency Modulation
What is a communication at a distance through technology?
telecommunication
What are two waves that we created and observed in class?
Compression and transverse
Is there sound in space? Why or why not
No medium (air, water, or substantial material)
What does a spectroscope reveal about light?
spectrum
To send a sound wave, communication devices start with a standard __________ wave.
Carrier wave
What is a regular pattern of motion?
oscillation
How can you calculate the wavelength if you know the distance between two adjacent nodes?
The distance between nodes is half of the wavelength. Multiply node-to-node distance by 2.
What kind of wave is formed when a medium is pushed or squeezed closer together?
Compression wave/longitudinal wave
What does a filter do?
It blocks out all other colors that the color of the filter.
After a sound wave has been sent from one device to another, what is the process called?
Demodulation
What is a compression wave generated by an earthquake that travels quickly through solids and liquids?
Primary wave (P-Wave)
