A LASIK vision-correction system uses a laser that emits 10-ns-long pulses of light, each with 2.4 mJ of energy. The laser beam is focused to a 0.85-mm-diameter circle on the cornea. - Part A What is the electric field amplitude of the light wave at the cornea? Express your answer to two significant figures and include the appropriate units. HA Eo = Value Units
