Final answer:
The energy of a photon with a wavelength of 630 nm is 3.14 eV.
Step-by-step explanation:
The energy of a photon can be calculated using the formula:
E = hc/λ
Where E is the energy of the photon, h is Planck's constant (6.626 × 10^-34 J·s), c is the speed of light (3.00 × 10^8 m/s), and λ is the wavelength of the photon. To find the energy of a photon with a wavelength of 630 nm (or 630 × 10^9 m), we can plug the values into the formula:
E = (6.626 × 10^-34 J·s)(3.00 × 10^8 m/s) / (630 × 10^-9 m) = 3.14 eV
