Final answer:
The energy of photons with the given wavelength can be calculated using the formula E = hf = hc/λ. The energy can be expressed in electron volts (eV) using a conversion factor. For example, if the wavelength is 0.5 μm, the energy of the corresponding photon is 1.549 eV.
Step-by-step explanation:
The energy of photons with the wavelength you found in part (c) can be calculated using the formula E = hf = hc/λ, where E is the energy of a single photon, h is Planck's constant, c is the speed of light, and λ is the wavelength. To find the energy in electron volts (eV), you can use the conversion factor that 1 eV = 1.602×10-¹9 J.
For example, if you found a wavelength of 0.5 μm (blue-green), you can calculate the energy of the corresponding photon as follows:
E = (6.626 × 10-34 J·s)(3.00 × 10^8 m/s) / (0.5 × 10^-6 m) = 2.484 × 10^-19 J = 1.549 eV.
