11.1: Force on a Disk
Force = pressure * area
Radiation Pressure = Intensity / c
Intensity = Power / Area
Radiation Pressure = (A+2R)(Power)/(area*c)
~Force = (A+2R)(Power)(pi*Rd2)/(pi*Rb2*c)

11.2: Electromagnetic Waves
w=(2*pi*c)/lambda
E2=2Z0I
B=E/c
B0=sqrt(2Z0I)/c
B=-B0cos(-wt)
~B=-sqrt(2Z0I)*cos(-2*pi*c*t/lambda)/c

11.3: Linearly Polarized Waves
a)-z
b)E0=sqrt(2Z0I)
c)k=(2*pi*f)/c
d)w=2*pi*f
e)T=1/f
f)B1=E0/c*sqrt(2)
  B2=-E0/c*sqrt(2)
  B3=0

11.4: Speeding Car
a)delta.f=(f/Q)/2 [convert to kHz]
b)v=c-cf'/f
  f'=your car frequency
  f=tower frequency
c)lambda=c/f
d)t=x/c
