Ответ:
The motion towards or away from us based on the Doppler effect and corresponding red shift or blue shift.
Explanation:
The emission and absorption spectra demonstrates the lines where light has been absorbed by the atoms. The spikes can be observed due to atoms releasing photons at those wavelengths. Infrared and ultra violet waves can be observed during spectroscopy.
Ответ:
The correct name for the following compound is
2 - methylbicyclo[4.3.0]nonane
Explanation:
Rule 1
Numbering of bicyclic compound is done from bridgehead carbon
Rule 2
The system is numbered with one of the bridgeheads, numbering proceeding by the longest possible path to the second bridgehead.
Name of the given bicyclic compound is 2 - methylbicyclo[4.3.0]nonane
