Units of energy Units of energy Because energy is defined via work, the SI unit for energy is the same as the unit of work – the joule (J), named in honor of James Prescott Joule and his experiments on the mechanical equivalent of heat. In slightly more fundamental terms, 1 joule is equal to 1 newton metre and, in terms of SI base units An energy unit that is used in atomic physics, particle physics and high energy physics is the electronvolt (eV). One eV is equivalent to 1.60217653×10 J. In spectroscopy the unit cm = 0.000123986 eV is used to represent
Scientific echosounder vegetation and algae - with the appropriate software. Hardware Software Scientific echosounder A scientific echosounder is a device which uses sonar technology for the measurement of underwater physical and biological components—this device is also known as "scientific sonar". Applications include bathymetry, substrate classification, studies of aquatic vegetation, fish, and plankton, and differentation of water masses. Scientific echosounder equipment is built to exacting standards and tested to be stable and reliable in the transmission and receiving of sound energy under the water. Recent advances have led to the development of the digital scientific echosounder, further enhancing the reliability and precision with
