The energy of a photon that has a frequency of 8.21 × 10¹⁵ s^-1 is ________ J. A)8.08 × 10^-50 B)1.99 × 10^-25 C)5.44 × 10^-18 D)1.24 × 10⁴⁹ E)1.26 × 10^-19

Question

Quizplus · Accepted Answer

The energy of a photon is calculated using the formula E = hν, where h is Planck's constant (6.626 × 10^-34 J·s) and ν is the frequency. Substituting the given frequency, E = (6.626 × 10^-34 J·s) × (8.21 × 10^15 s^-1) = 5.44 × 10^-18 J.
