Aplane monochromatic radio wave (λ = 0.4 m) travels in vacuum along the positive x-axis, with a time-averaged intensity i = 25 w/m2. suppose at time t = 0, the electric field at the origin is measured to be directed along the positive y-axis with a magnitude equal to its maximum value. what is bz, the magnetic field at the origin, at time t = 2 ns? bz =

Explanation:

= Permittivity of free space =

c = Speed of light =

= Wavelength = 0.4 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

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
