Light has a wavelength of 5.8 *10² nm. What is the energy of a photon of this light? A) 2.62 *10¹⁸ J B) 3.81 * 10^-²⁰ J C) 1.28 * 10^-¹⁸ J D) 1.14 *10^-¹⁹ J E) 3.42 * 10^-¹⁹ J

Question

Quizplus · Accepted Answer

The energy of a photon can be calculated using the formula E = hc/λ, where h is Planck's constant (6.626 x 10^-34 J·s), c is the speed of light (3.00 x 10^8 m/s), and λ is the wavelength in meters. Converting 5.8 x 10^2 nm to meters gives 5.8 x 10^-7 m. Substituting these values into the formula gives E ≈ 3.42 x 10^-19 J.
