The energy of a photon that has a frequency of 1.821 × 10¹⁶ s^-1 is __________ J. A)5.44 × 10^-18 B)1.99 × 10^-25 C)3.49 × 10^-48 D)1.21 × 10^-17

Question

Quizplus · Accepted Answer

The energy (E) of a photon is given by the formula: E = hν, where h is Planck's constant and ν is the frequency of the photon. 
Therefore, E = (6.626 × 10^-34 J·s)(1.821 × 10^16 s^-1) 
= 1.21 × 10^-17 J 
which is closest to Option D (1.21 × 10^-17 J).
