What technique did Leavitt's discovery vastly surpass in distance measurement?
Spectroscopy
Triangulation
Doppler effect
Laser Interferometry
Answer
Leavitt's discovery vastly surpassed triangulation in distance measurement. Leavitt discovered that Cepheid variables, a type of star that pulsates in a regular way, have a direct relationship between their luminosity and the period of their pulsation. This meant that by measuring the period of a Cepheid variable, it was possible to determine its absolute luminosity.
