Dr Bob, Thanks for the help with the conversion. I was missing the solution on two fronts. One was the wavelength factor and the other was the MegaHertz. Do you know where I can find more information on "wavelength of the radiation" ? There is not a lot of specific d...
I'm having a difficult time with the Conversion Units in my equation. Attempting to answer this question: My cell phone has an antenna about 10.00cm long. If this is one quarter of the wavelength of the radiation, at what frequency in Megahertz does it operate? Note that c...
My cell phone has an antenna about 10.00cm long. If this is one quarter of the wavelength of the radiation, at what frequency in Megahertz does it operate? Note that cell phones, like radio, transmit sounds via electromagnetic waves which travel at the speed of light or 3x108m/s
