How many photons are contained in a burst of yellow light (589 nm)from a sodium lamp that contains 623 kJ of energy? A) 2.10 × 10¹³ photons B) 3.06 × 10³⁰ photons C) 1.85 × 10²⁴ photons D) 4.03 × 10²⁸ photons E) 2.48 × 10²⁵ photons

Question

Quizplus · Accepted Answer

The energy of a single photon can be calculated using E = hc/λ. Using Planck's constant (h), the speed of light (c), and the given wavelength (λ), the energy per photon is calculated. Dividing the total energy (623 kJ) by the energy per photon gives the number of photons.
