The Niagara Falls Power Company was the first to adopt his invention in the exploitation of hydro power, proving the universal adaptability of alternating current. Hertz before him had already transmitted and received radio signals in the microwave range over short distances. Marconi received the 1909 Nobel prize in physics for his achievement. These Raman spectra can be used to investigate and identify molecular structure. Based on the reflection of shortwave radio waves, radar pinpoints a moving object's location by measuring the time elapsed between emitted and reflected pulses as well as their direction.
Spectroscopy plays an integral part in modern forensic science in the identification of substances.
Spectra are featured on this Canadian stamp commemorating the 100th anniversary of the Royal Canadian Mounted Police.
