In an experiment, a photon with a frequency of 7 x 10^14 s^-1 was absorbed by a sample. What is the approximate energy of this photon?
A) 5 x 10^-19 J
B) 1 x 10^-15 J
C) 2 x 10^6 J
D) 1 x 10^48 J

Answer

The energy of a photon can be calculated using the formula:

E = h * f

where E is the energy, h is Planck's constant (6.626 x 10^-34 J·s), and f is the frequency.

Given f = 7 x 10^14 s^-1, the energy E is:

E = 6.626 x 10^-34 J·s * 7 x 10^14 s^-1 = 4.6382 x 10^-19 J

The closest answer is:

  1. A) 5 x 10^-19 J
