Wave Behaviors
This behavior occurs when a wave hits a metal surface and "bounces" back at the same angle.
Reflection
These waves have the longest wavelength and lowest energy on the spectrum.
Radio Waves
This model explains that light behaves as both a wave and a particle.
Wave-Particle Duality
When a crest meets a crest, this type of interference occurs. The resulting wave has a greater amplitude (more energy) then the original waves.
Constructive Interference
When an electron oscillates in a wire it will produce what?
An electromagnetic wave
This occurs when a wave bends as it moves from air into glass.
Refraction
This radiation is associated with heat and is just below visible red.
Infrared
These "packets" of light energy were described by Einstein in 1905.
Photons
A 5cm crest meets a 3cm trough. What is the resulting amplitude? And What type of a wave interaction is this?
2 cm, destructive
Noise Canceling headphones use this wave Behavior to cancel out noise.
Destructive interference
This behavior allows WiFi to "bend" around a door frame or corner.
Diffraction
This frequency range passes through soft tissue but not bone.
X-rays
This effect describes light ejecting electrons from a metal. This is how solar panels work.
Photoelectric Effect
What is a benefit of using fiber optics rather than copper wire
Fiber Optics are not affected by electromagnet interference like electrons moving through a metal wire.
A rainbow is primarily caused by this wave Behavior
refraction
The sky is blue because the atmosphere causes this behavior.
Scattering
This is the range of wavelengths (in nm) the human eye can see. (Use a Picture of the EM spectrum)
400nm to 700nm
This signal uses discrete states to stay clear over distances. The states are translated into what when being written on a hard disk drive?
Digital signal is translated into magnetic field directions on the hard drive.
Two waves are "out of phase" by 180°. What happens to the signal?
Total Destructive Interference - The waves cancel out
When waves move through a medium and vibrate the molecules therefore transferring some of their energy from the wave to the medium we call this what?
Absorption
The property of fiber optics that allows the light to travel through the glass "wire"
Total Internal Reflection
This radiation has enough energy to remove electrons from atoms.
Ionizing
This "rate" determines snapshots taken per second of a wave.
Sample Rate
As a car horn comes closer to a stationary observer, the sound seems to change. Explain what you hear and what is happening to the sound waves. Finally what is this called?
When the sound approaches the pitch appears to go up. The sound waves bunch up (from the perspective of the observer), frequency appears to increase. This is called the Doppler Effect.
Low attenuation means that the strength of a signal will not degrade much over long distances.
