The energy of a photon is usually given to solve these types of problems. = (3.0 x 10^8 m/s) / (4.5 x 20^9 s^-1) k = 2 Would it not make sense that in order to convert energy in joules to wavenumber we multiply E by 2 h c = 1 c. So my question is why in converting energy from the units of joules to the units of wavenumber do we divide E by h c rather than by c quantum-mechanics dimensional-analysis Share Cite Improve this question Follow Thanks! We use Joules, kilograms, and meters per second as our defaults, although any appropriate units for mass (grams, ounces, etc.) The next equation we need to consider is the Planck-Einstein relation: Manipulation of the formulas is then required. Now let us see how we can calculate the wavenumber for a light wave if its wavelength is 700 nm.

Just use our wavelength calculator in the following way: Remember that the frequency doesn't change when passing from one medium to another. Energy Unit Conversions Send feedback | Visit Wolfram|Alpha. . The resulting number is the energy of a photon. Calculation Theory Photon Energy and Wavelength The energy of light (or photon energy), E, is inversely proportional to the wavelength by the equation: E = hc/ l (equation 1) where h is Planck's constant (6.6261 x 10 -34 J*s) and c is the speed of light (2.9979 x 10 8 m/s). How you can Convert Nanometers to Joules If you know the frequency of a wave traveling through a medium you can calculate how far it is between each crest of the wave or each trough of the wave. Its unit is meter per second. Calculating wavelength is dependent upon the information you are given. 2. Wavelength can be calculated using the following formula: wavelength = wave velocity/frequency. Wavelength Calculator = v/f In spectroscopic studies and chemistry, the term wavenumber (or wave number) represents the number of wavelengths per unit length. The amplitude of a wave is the maximum distance from the equilibrium position, i.e., the distance between the central line and the peak of the crest or bottom of the trough. To calculate wavelength, use the formula wavelength = speed divided by frequency. It's easy! Calculate the unknown variable in the equation for kinetic energy, where kinetic energy is equal to one half times the mass multiplied by velocity squared; KE = 1/2 * mv^2.

The result will then be displayed in the answer box along with a dynamic conversion scale to show how wavelength varies for different photon energies, above and below the entered value. By the energy-momentum relation, photons are relativistic particles since they travel at the speed of light. What is the relationship between wavelength and frequency? Divide the speed of light, equal to 299,792,458 meters per second, by the photon's energy. Microwave ovens typically operate with waves with frequencies of about 2.45 GHz. Energy Conversion Calculator Simply use the energy required for ionization and solve for the corresponding wavelength. Simply select these units in the dropdown list next to each field. Some examples of how to use our frequency to wavelength calculator. 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.
