Define "wave."
A disturbance that carries energy through matter or space.
If frequency goes up, what happens to wavelength?
Wavelength does DOWN when frequency goes UP.
The waves with the HIGHEST wavelength and LOWEST frequency are _______________.
Radio Waves.
Who is Roy G. Biv?
No one, it's an acronym for the colors of the rainbow - red, orange, yellow, green blue, indigo, violet
What kind of waves come from the sun?
Ultraviolet (UV)
What kind of wave does NOT need a medium to travel?
Electromagnetic waves.
Define "wavelength" in terms of a COMPRESSIONAL wave.
The distance from compression to compression or rarefaction to rarefaction.
Why do we wear lead vests for protection during doctor/dentist visits?
X-rays cannot penetrate the vests.
What color from the visible light spectrum has the HIGHEST frequency?
Violet
What is the speed of sound?
300,000,000 m/s
What kind of wave is this AND what is being shown in the yellow box?
A transverse wave showing the (+) amplitude.
What is the equation of "speed?" Include units.
Speed (m/s) = wavelength (m) X frequency (Hz)
Remote controls are an example of WHAT kind of wave?
Infrared Rays.
Explain dispersion.
When white light is refracted through a prism, we see the light at all possible wavelengths giving us a rainbow.
What must occur to hear a sonic boom?
You must be traveling faster than the speed of sound.
A seismic wave, or a wave that occurs after an earthquake, is an example of WHAT KIND of mechanical wave?
Compressional Wave
What is the wavelength for the color GREEN? Include units.
What type of wave carries the MOST energy?
Gamma rays.
What color from the visible light spectrum carries the lowest energy?
Red
What is the "Doppler Effect?"
The "perceived" change in frequency of an object's sound when the source and the observer are in motion relative to each other.
EX: Firetruck siren

Draw a compressional wave and label its 3 parts.
A wave traveling at 230 m/sec has a wavelength of 2.1 meters. What is the frequency at which this wave is traveling?
230m/s / 2.1m = 109.24 Hz
List all the waves in the electromagnetic spectrum in order from LOWEST wavelength to HIGHEST wavelength?

Infrared and Ultraviolet.
Multiple part question - must answer all parts correctly for point.
In 1962, nuclear physicist, Dr. Robert Banner was working on creating a G-Bomb for the U.S. military. During a test run, Dr. Banner was, instead, exposed to the bomb's effects. What is a G-Bomb and what was the result of exposure to it?
Gamma Radiation Bomb - Dr. Banner became the hulk.
