What is the wavelength of the radiation whose photons have 1 eV of energy? A)8.1 × 10^-4 nm B)1240 nm in the infrared range C)1.24 × 10^-6 nm, gamma rays D)124 nm in the ultraviolet range

Question

Quizplus · Accepted Answer

The energy of a photon (E) is related to its wavelength (λ) by the equation E = hc/λ, where h is Planck's constant (6.626 × 10^-34 m^2 kg / s) and c is the speed of light (3.00 × 10^8 m/s). Using the energy value of 1 eV (1 electronvolt = 1.602 × 10^-19 joules), and converting the units appropriately, the wavelength of the radiation is found to be approximately 1240 nm, which falls within the infrared range of the electromagnetic spectrum.
