What is the Maxwell-Boltzmann Distribution
100
These lines are always perpendicular to electric field lines.
What are "Equipotential lines' or "Isolines"
100
This is the reason that terminal voltage of a battery is often less than the nominal voltage.
What is Internal Resistance
100
Change the strength of the B-field
Change the angle between the loop and the B-field
Change the area of the loop
What are 3 ways to change magnetic flux
100
The location of a virtual image can be measured using this technique that involves placing a marker at the estimated location and looking at it from different perspectives.
What is Parallax
100
Boundary reflection of waves is important to thin film interference. This is the phase of a reflection from a ray trying to go from a more dense to a less dense medium.
What is "In Phase"
100
THe work function of a metal will be equal to the y-intercept on a graph of ______ vs blank ______.
What is Maximum KE of emitted electrons vs frequency.
200
This process occurs so quickly that noe heat transfer occurs.
What is "adiabatic"
200
This physics term is commonly known as "voltage".
What is "Electric Potential"?
200
The presence of a dielectric in a capacitor cahnges the stregth of the electric field in this way.
What is "It weakens the field"
200
The name of this principle in physics: Induced EMF will result in magnetic flux that opposes the change in outside flux that induced it.
What is Lenz's Law
200
This is when you make the image distance negative
What is When it's on the same side of the lens as the object, OR
It's virtual
200
This is the distance between two compressions in a longitudinal wave.
What is wavelength
200
The difference between the total mass of a nucleus and the sum of the masses of its constituent parts.
What is Mass Defect
300
This states that the total energy in a gas sample is equal to heat added plus work done.
What is the 1st law of thermodynamics
300
This tells us the amount of electric force that is acting per unit of charge.
What is an electric field.
300
It's what this symbol stands for:
What is "Electromotive Force"
300
Long ago, people observed magnetic interactions with this mineral and Earth's magnetic field.
WHat is Lodestone. (Magnetite is also acceptable)
300
THese lenses are thinner in the middle than at the edges.
What are diverging lenses
300
This is determined solely by the propertied of the medium a wave travels through,
WHat is wave speed
300
This is when a photon transfers some of its momentum to an electron.
What is Compton Scattering
400
This is equal to the ration of useful work coming out of an engine to the energy that was put into it.
What is "thermal efficiency"?
400
Electric field lines point from:
What is "from positive to negative"
400
Conservation of charge is expressed in this circuit rule.
WHat is Kirchhoff's Junction Rule
400
This is the reason a magnetic field can't do work on a moveing charged particle.
What is "because the force acts perpendicular to the motion"
400
This law about bending light was actually discovered 640 years earlier in Baghdad, but we know it by this European discoverer's name
What is Snell's Law
400
Differences in path length that light rays travel after passing through a diffraction grating cause this phenomenon.
WHat is interference
400
This constant relates an object's temperature with the peak wavelength of its emitted EM radiation
What is Wien's Constant.
500
When two objects come into thermal contact and reach thermal equilibrium, the entropy of the system changes in this way.
What is "Increase"
500
A proton and an electron are released from rest, from a point midway between parallel charged plates. This one will be traveling faster when it strikes a plate.
What is the electron
500
The amount of charge on capacitor plates is all the same if the capacitors are connected in:
What is Series
500
Using the right hand rule (the way we learned it, anyway) this digit points toward the magnetic field.
What is the bird (middle)
500
Rays that travel parallel to the principal axis and pass through a lens will all pass through this point.
What is a focal point
500
Single slit and double slit diffraction produce similar patterns, but from a slightly different mechanism. For this typr of diffraction, we look for the dark fringes.
What is "Single Slit Diffraction"
500
This constant is equal to the natural log of 2 divided by half-life.
What is the Decay Constant
