Wavelength nm to energy calculator
Measuring Planck’s Constant Using the Photoelectric Effect
If no electron is emitted, press to return to the main menu and change your wavelength to a more energetic photon (lower wavelength = more energy). Try decreasing your wavelength by 100 nm and running the simulation again to see if an electron is emitted. Once you have electrons being emitted you are ready to start.

One of the wavelengths emitted from hydrogen is 486.133 nm. Convert this wavelength to energy in J using E=hν where E is energy, h is Planck’s constant (6.62607 x 10-34 J·s) and ν is frequency (c= νλ). The energy represents the difference in energy between the two levels the electron is transitioning between. 3. Birds of a Feather

Ex. Calculate the frequency of red light with wavelength 700 nm and the frequency of violet light with wavelength 400 nm. These answers can also be written as where 1 THz = 1 terahertz = 1012 Hz. An electromagnetic wave, like any periodic wave, has a frequency f and a wavelength ( that are related to the speed v of the wave by v = f(, Equation ...

Several minutes will be required to run the tests. You will use the calibration data at 486.00 nm and 656.10 nm. For example, if the report reads that the 486.00 nm line was found at 486.02 nm, then the wavelength reading is 0.02 nm high and hence a correction of –0.02 nm needs to be added to all wavelengths in the near vicinity of 486 nm.
