SUMMARY

The wavelength of an 83 keV photon is calculated to be 4.99 E-20 meters. To derive this value, one must use the appropriate version of Planck's constant, specifically in eV·s, rather than J·s, to ensure unit consistency. The conversion from keV to eV is necessary, as 1 keV equals 1000 eV, leading to a total energy of 83000 eV for the photon. This calculation emphasizes the importance of using the correct constants and units in photon wavelength calculations.

PREREQUISITES
  • Understanding of photon energy calculations
  • Familiarity with Planck's constant in different units
  • Knowledge of energy unit conversions (keV to eV)
  • Basic principles of wave-particle duality
NEXT STEPS
  • Study the derivation of the photon wavelength formula using energy and Planck's constant
  • Learn about the implications of using different units for physical constants
  • Explore the relationship between energy, frequency, and wavelength in quantum mechanics
  • Investigate applications of photon wavelength calculations in fields like spectroscopy
USEFUL FOR

Physicists, students studying quantum mechanics, and anyone involved in photon energy calculations or related research.

What is the wavelength of a 83 keV photon?

does it matter whether or not you convert to eVs? or can it remain keV?

i have it as 83000eVs=6.6E-34*3E8/lambda

Think about it. What is one of the things that the proportionality constant (Planck's constant in this case) does? Make the units work out. So it has to be the version of Planck's constant that is expressed in the right units to do so, not J*s in this case, but eV*s. Well, if it isn't, then convert it.

Edit: Oh, that wasn't your question, but from the looks of it, it's a good thing I brought it up. Take a look at the constant you are using.
 
ya that helped ty4.14E-15evsec/83000eV
wavelength is 4.99 E-20
