这是物理问题吧1) Springfield's "classic rock" radio station broadcasts at a frequency of 102.1 MHz. What is length of radio wave in meters? 某电台频率是102.1兆赫兹，求波长102.1*10^6=v/l=3*10^8/l波长l=2.94 m2) A beam of light has a wavelength of 506 nanometers. What is the frequency of the lights?某种光波长506纳米，求频率频率=光速/波长=3*10^8/(506*10^-...
