Homework Statement




A laser produces an average power of 7.0 W in a light beam 1.0 mm in diameter. Find (a) the average intensity and (b) the peak electric field of the laser light


Homework Equations



Intensity = P/ A
Unsure about part B

The Attempt at a Solution



For part A I did P/( ∏ * r^2) which came to be 7W/( ∏ * .0005^2) which came to 8912676 w/m^2

But I need help finding out how to do part B. Any help would be great.
