Sound in air = 340 m/s Decibels (dB) conversion calculator. where 'e' is energy (joules), 'f' is frequency (cycles per second), 'h' is Planck's constant (6.6260695729 x 10-34 Joule*seconds) and wavelength λ is in meters. It is always important to be keen while entering the values in the open text field since the converter gives accurate results depending on the input. This calculator majorly deals with conversions from electron volts to energy in joules. How to calculate the energy of a photon. ›› Definition: Joule. The hertz (symbol Hz) is the SI unit of frequency. ; This equation gives us an energy of a single, indivisible, quanta of light and we can think of light as a collection of particles. It is characterised by either λ or energy of light (E). The wavelength result is 3 m. Most common velocities: Light in vacuum (air) = 300,000 km/s. It is named in honour of the German physicist Heinrich Rudolf Hertz who made some important contributions to science in the field of electromagnetism. E = h * c / λ = h * f,. To convert between Megahertz and Joule/meter you have to do the following: First divide 1000000 / 1 = 1000000.. Then multiply the amount of Megahertz you want to convert to Joule/meter, use the chart below to guide you. Planck's equation is used to describe the energy of light using wavelength (λ). Light in water = 225,000 km/s. Wave velocity (m/s) =Wavelength (m) * Frequency (Hz) Example calculation. MEGAHERTZ TO JOULE/METER (MHz TO J/m) FORMULA . The exponential notation: e+08 for 10 8 and e-11 for 10-11, may be used for the initial input, but is not necessary. where. Decibels to watts, volts, hertz, pascal conversion calculator. The fact that the calculator is free makes it widely accessible, and you can use it at any time. To use the following calculator, first select the units for each entry. Conversion Chart Original Nomograph - Maury Microwave Corp. '97 Nomograph conversion from λ = 1 mm to 10 nm Nomograph conversion from λ = 1000 m to 1 cm Remember: Mega-Hertz = MHz = 10 6 Hz Giga-Hertz = GHz = 10 9 Hz Tera-Hertz = THz = 10 12 Hz Peta-Hertz = PHz = 10 15 Hz milli-meters = mm = 10-3 m microns = μm = 10-6 m nano-meters = nm = 10-9 m E is the energy of a photon; h is the Planck constant,; c is the speed of light,; λ is the wavelength of a photon,; f is the frequency of a photon. To convert hertz to joules, simply multiply the number in hertz with the value of the conversion factor 'x.' Hertz, which is symbolized by Hz, is SI's unit of frequency. This electromagnetic spectrum calculator converts between four parameters that define electromagnetic radiation: the frequency, the wavelength, the photon energy, and the temperature of a radiating black body for which the radiation curve reaches its maximum (peak wavelength). Let’s take for instance the case of a wave with a frequency of 56 Hz going through a material at a speed of 168 m/s. Then enter a number value in one of the display boxes, and press the Calculate button, The corresponding conversions will appear in exponential form in the remaining boxes. Set the quantity type and decibel unit. The joule (symbol J, also called newton meter, watt second, or coulomb volt) is the SI unit of energy and work. Wavelength to Energy Calculator . Conversion from Hz to J : Conversion equation: (1 Hz)h = x J x = {h} Value of conversion factor: x = 6.626 070 15 x 10-34 : Your input value: 1.000 000 000 000 00... Hz : Your converted value: 6.626 070 150 000 00... x 10-34 J : Note: {Q} is the numerical value of Q when Q is expressed in SI units Online energy of light with wavelength calculator to calculate energy in Joules, Kilojoules, eV, kcal. The Planck's equation is. The conversion factor value is 6.62606957(29) x 10^-34. Enter the values in one or two of the text boxes and press the corresponding Convert button: Convert dB, dBm, dBW, dBV, dBmV, dBμV, dBu, dBμA, dBHz, dBSPL, dBA to watts, volts, ampers, hertz, sound pressure. As always, we have written a calculator to make the work a little easier for you. Photon is the tiny fundamental part of the visible light.
