What is the energy of a photon with wavelength of 670.8?
Sliva [168]
<span>The velocity of a wave is calculated by v = λf. From this equation we can take the frequency f = v / λ and substitute in the energy equation to find a new equation for the calculation of the energy from the wavelength: E = hc / λ</span>


To calculate the photon energy, in eV (Electrovolt), when we have the value of the wavelength λ (necessarily given in Å - angstrom), we use an alternative equation given by:
E =  \frac{12400}{\lambda}

Data: 670.8 Å

Solving:
E = \frac{12400}{\lambda}
E = \frac{12400}{670.8}
\boxed{E \approx 18,4eV}
