the speeds of the waves are the same, but the wavelength of A is half the wavelength of B. |
||
the wavelengths of the waves are the same, but the speed of A is half the wavelength of B. |
||
both speed and wavelength are the same for both waves. |
||
it is impossible to determine the speed and wavelengths without knoing the type of waves. |

- The maximum magnetic field strength of an electromagnetic field is 9 ✕ 10−6 T. Calculate the maximum electric field strength (in kV/m) if the wave is traveling in a medium in which the speed of the wave is 0.68c.arrow_forwardWhich of the following correctly ranks the categories of electromagnetic radiation in order of increasing wavelength (i.e, short to long)? Microwave < Radiowave < X-ray Radiowave < Microwave < Infrared wave X-ray < UV light < Gamma rays Visible light < Infrared wave < UV light Gamma Rays < UV light < Radiowavearrow_forwardAn electromagnetic wave with an amplitude of 8.00 V/m boils a cup of water in 4.00 minutes. (The units for the amplitude are here because we always need units, but they are not relevant to answering the question). If the amplitude was increased to 16.0 V/m, but everything else (e.g., frequency, distance of cup from source etc.) stayed the same, how long would it take to boil the same cup of water? Enter your answer in minutes.arrow_forward
