Physics Lecture Notes Flashcards

Vocabulary flashcards based on physics lecture notes, focusing on key terms and definitions.

r

Distance between two charges.

E

Electric field.

E = lambda / (2 * pi * epsilon_0 * r)

Electric field due to an infinite charged wire.

Gauss's Law

Relates electric field flux to enclosed charge.

Qinner surface = -Qcenter

Charge on the inner surface of a conductor is equal in magnitude and opposite in sign to the charge at the center.

WAB

Energy required to move a charge between two points A and B.

ΔVAB

Change in potential between points A and B.

V = kQ/r

Potential due to a point charge.

Capacitance (C)

Measure of a capacitor's ability to store charge.

Q = CV

The relationship between charge, capacitance, and voltage (Q = CV).

Power (P)

Rate at which energy is transferred or converted.

Refraction

The bending of light as it passes from one medium to another.

Snell's Law

n1sin(i) = n2sin(r)

Critical Angle (θc)

The angle of incidence at which total internal reflection occurs.

Apparent Depth

Ratio of the apparent depth to the actual depth.
