Question

The magnetic field in an electromagnetic wave has a peak value given by B = 3.5?T .

Part A For this wave, find the peak electric field strength. Express your answer using two significant figures. E =   kV/m   SubmitMy AnswersGive Up Part B Find the peak intensity. Express your answer using two significant figures. I =   kW/m2   SubmitMy AnswersGive Up Part C Find the average intensity. Express your answer using two significant figures. Iav =   kW/m2

Answer 1

Please rate my answer..

Answer 2

apply Intensity I = power/area = Emax^2 /2uoC

a,lso Emax = Bamx * C

Emax = 3.5e-6 *3e8

Ema x=1050 N/C

Epeak = 1.050 KN/C

-------------------------------------------

so I = 1050*1050/(4pie-7*3e8)

I = 2.929 KW/m^2

--------------------------------------------

Iavg = 2.929/2 = 1.462 KW/m^2
