Homework Statement
What is the maximum value of the electric field E at 1.0 m from a 100 W light bulb radiating in all directions?
Homework Equations
I feel like I should use this equation: I=(1/2)(8.85x10^-12)(c)E^2
The Attempt at a Solution
When I used that equation, I didn't get the right answer. But I guess I'm confused since intensity is W/m^2 and we're not given the unit area.
