Question

# What is the energy of a proton if it is associated with light with a wavelength of 6057.8 A?

Answer

The energy of the proton is 3.312×10∧−12erg.

The calculation of the energy of a photon involves the equation E=hc/λ where h is Planck's constant, c is the speed of light, and λ is the wavelength of the light. Substituting the given values into the formula, we get E=6.624×10∧−27 erg-sec ×3×10∧10 cm/sec / 6057.8 A = 3.312×10∧−12erg. Therefore, the energy of the proton associated with light with a wavelength of 6057.8 A is 3.312×10∧−12erg.
