Which is true about the detected frequency and wavelength of light that is emitted by a source that is moving toward the detector? The frequency and wavelength are both greater than the proper values, as measured on the source. The frequency and wavelength are both smaller than the proper values of the emitted light, as measured on the source. The frequency is greater than the proper frequency and the wavelength is smaller than the proper wavelength. The frequency is smaller than the proper frequency and the wavelength is greater than the proper wavelength.
