Aplane monchromatic radio wave (lambda = 0.3 m) travels in vacuum along the positive x-axis, with an intensity i = 45 w/m2. suppose at time t = 0, the electric field at the origin is measured to be directed along with positive y-axis with an amplitude equal to its maximum possible value. what is bz, the magnetic field at the origin, at time t = 1.5 ns?

Explanation:

= Permittivity of free space =

c = Speed of light =

= Wavelength = 0.3 m

T = Time period

f = Frequency

= Electric field

Intensity of electric field is given by

Magnetic field is given by

Magnetic field in the z direction is given by (x=0)

The magnetic field at the origin is

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
