PHYS 1112L Lab 15: Reflection and Refraction
Theory
o Angle of incidence = angle of reflection
o Refraction: light ray crosses surface separating two media with different indices
of refraction

Lab 12: Equipotential Lines
I.
Introduction:
The purpose of this experiment was to understand how equipotential lines and electric fields
function. By determining the force on charged objects due to surrounding charges, one can cr

PHYS 1112L Lab 13: Ohms Law
Theory
o Ohms Law: V = IR
Diodes and resistors do not obey this law
o Series Circuit:
Req = R1 + R2
o Parallel Circuit
1/Req = 1/R1 + 1/R2
o Kirchhoffs Rules
Node: sum of all currents into a node = 0
I1 + I2 + I3 = 0
