It is false, that radio waves travel at the same rate as high energy visible light waves through air? Yes or no?

We consider an electromagnetic wave with peak magnetic field strength Bo projected on an area A. How will the power be affected if Bo is tripled and the area is divided by 3? the power will be multiplied by a factor 9 O there is not enough information to determine how the power will be affected O the power will stay constant O the power will be divided by 3 O the power will be tripled

How is the potential energy associated with an electromagnetic wave shared between the electric and magnetic fields? O there is no potential energy associated with an electromagnetic wave more of the energy is in the electric field it is equally shared between them O more of the energy is in the magnetic field

The energy flow to the earth from sunlight is about 1.4 kW/m2.(a) Find the maximum values of the electric and magnetic fields for a sinusoidalwave of this intensity. (b) The distance from the earth to the sunis about 1.5 * 10^11 m. Find the total power radiated by the sun.

How much energy (in Joules) does a green light have if its wavelength is 513 nm? Assume the light is traveling through a vacuum.

At what conditions will EM waves be able to transmit through a conductor?

#3: A certain 60.0 Hz AC power line radiates an electromagnetic wave having a maximum electric field strength of 13.0 kV/m. A) what is the wavelength of this very low frequency EM wave? B) What is its maximum magnetic field strength?
