intensity off. Electromagnetic welcome. Burton is the original energy Regine er ge Times the speed of light so they're branded energy in terms of a letter. Me electric field is given by one or two. It's alone, UH, times the electric field square times to see the electric field here, given he's 1 25 walls for meter so we can write one or two 1 25 square. We'll keep its alone constant See constant and dividing 1 25 square by two gives a seven eight 12.5 so we'll nod. Done. See, this is our intensity. And that's the problem. Thank you.
