Answer all parts with explanation, please. Thank you!

During normal beating, a heart creates a maximum 4.1-mV potential across 0.315 m of a person's chest, creating a 0.95-Hz electromagnetic wave. During normal beating of the heart, the maximum value of the oscillating potential difference across 0.315 m of a person's chest is 4.1 mV. This oscillating potential difference produces a 0.95-Hz electromagnetic wave. What is the maximum electric field strength, in volts per meter, of the electromagnetic wave? E = What is the corresponding maximum magnetic field strength, in teslas, of the electromagnetic wave? What is the wavelength, in meters, of the electromagnetic wave?

Explanation / Answer

(a) The maximum electric field strength

Emax. = (Vmax./d)

Emax. = (4.1*10^-3)/(0.315)

= 0.0130 V/C

(b) The maximum magnetic field strength in the electromagnetic wave is

Bmax. = Emax./c

= 0.01301/3*10^8
  
= 4.33*10^-11 T

(c) wave length of electromagnetic wave is

lambda = c/f

= (3*10^8m/s)/(1Hz)

lambda = 3*10^8 m
