Question

An atom emits a photon with a wavelength of 260 nmnm. By how much does the atom’s energy change?

Answer 1

An atom emits a photon with a wavelength of 260 nm, the atom’s energy change is 7.6 × 10^(-19) J.

What is photon energy relationship?

The energy of photon is inversely proportional to the wave length and directly propositional the speed of light.

Mathematically, photon energy relationship can be given as

$E = \frac{hc}{λ}$

E= Energy of photon

h= Plank's constant = $6.626$ × $10^{-34}$

c = 3 х $10^{8} m/sec.$

λ = $260$ × $10^{-9} m$

$E = \frac{hc}{λ}$

$E = 7.6$ × $10^{-19} J$

Thus, we find that the energy change is 7.6 × 10^(-19) J.
