A laser beam (λ=600nm) with an intensity of 150 mW/m^2 passesthrough three polarizers that make an angle of 40 degrees withrespect to each other.
a). What is the intensity of the beam after it passes throughthe three polarizers?
b). What is the amplitude of the magnetic field associated withthe incident beam?
c). What is the frequency of the incident electromagneticwave?
d). If the beam strikes an electron at rest, what is the maximumelectric force that the electron will experience?
