WebSep 22, 2024 · The relationship between the wavelength, frequency and speed of an electromagnetic wave is given by the equation: (8.1) c = λ × ν. Electromagnetic radiation also occurs as discreet packets of energy (or quanta) called photons. The energy per photon (in Joules) is given by the equation: (8.2) E p h o t o n = h × ν. WebAll the prepared energetic metal salts show excellent thermal stabilities, and the decomposition temperatures of EP-3, EP-4, and EP-5 are higher than 250 °C, due to the numerous coordination bonds of the complexes. Furthermore, the energy of formation of the nitrogen-rich salts were calculated utilizing heat of combustion.
