An 8.00-mW laser beam emits a cylindrical beam of single-wavelength sinusoidal light 0.600 mm in diameter. What is the maximum value of the magnetic field in the laser beam?
 
  (0 = 8.85  10-12 C2/N  m2, 0 = 4  10-7 T  m/A, c = 3.0  108 m/s)
  A) 20.5 T B) 17.2 T C) 12.4 T D) 15.4 T E) 9.24 T

Question 2

A pair of narrow slits, separated by 1.8 mm, is illuminated by a monochromatic light source. Light waves arrive at the two slits in phase, and a fringe pattern is observed on a screen 4.8 m from the slits.
 
  If there are 5.0 complete bright fringes per centimeter on the screen near the center of the pattern, what is the wavelength of the monochromatic light?
  A) 700 nm B) 650 nm C) 550 nm D) 600 nm E) 750 nm
