If the eye receives an average intensity greater than 100W/m^2 ,damage to the retina can occur. This quantity is called the damagethreshold of the retina.
What is the largest average power (in ) that a laser beam 1.50 indiameter can have so that it can be considered safe to viewhead-on?
What is the maximum value of the electric field for the beam inpart A?
What is the maximum value of the magnetic field for the beam inpart A?
How much energy would the beam in part A deliver per second to theretina?
Express the damage threshold in W/cm^2
