Old Vocabulary
What's a constraint?
A limitation or restriction
What is wavelength?
The distance from the start to the end of the wave
What is one major difference between energy transfer in a circuit and energy transfer in a microwave?
The distance energy can travel through
Which 2 particles that we've studied exhibit particle-wave duality?
Photons and electrons
What SI unit do we use to measure wavelength?
Meters
What is the difference between transmission and distribution lines?
Transmission = higher voltage over longer distances from power plant to substations
Distribution = lower voltage over shorter distances from substations to buildings
What is a subatomic particle?
A particle that is smaller than an atom
What holds particles together?
Is light a wave or a particle?
Both
What property of a circuit is measured in Ohms?
Resistance
What is amplitude?
The height from the center to the top/bottom of a wave
What travels from one end of a wave to the other?
Energy
Electromagnetic waves travel at what speed?
Speed of light 3x108 m/s
What SI unit do we use to measure frequency?
Hertz
What is a microgrid? How can they be beneficial to our community?
A power grid that powers a small, localized area. Should be more reliable
What is quantum mechanics?
the study of the "behavior" of subatomic particles
How does a microwave heat food? What happens to the area in the microwave?
It changes the electric field, making electrons move quickly
What is the name of the experiment that taught us about the particle-wave duality of light?
Double-slit experiment
What is the SI unit we use to measure wave speed?
m/s
What is the creation of a voltage in an electric conductor by way of a changing magnetic field?
Electromagnetic induction
What is particle wave duality?
The quality of acting as both a particle and a wave
What does a magnetron do?
Turns electric energy into electromagnetic radiation
