How does the wavelength (in a vacuum) of a high-frequency electromagnetic wave compare with a low-frequency electromagnetic wave?
 
  A) it is impossible to tell because frequency and wavelength are not related
  B) the lower-frequency wave has the longer wavelength because frequency and wavelength are inversely proportional to each other
  C) the two waves have the same wavelength because the wavelengths of all electromagnetic waves are the same
  D) the higher-frequency wave has the longer wavelength because frequency and wavelength are directly proportional to each other

Question 2
