What is the frequency of a photon having an energy of 4.91 × 10^-17? (c = 3.00 × 10⁸ m/s,h = 6.63 × 10^-34 J · s) A)2.22× 10²⁵ Hz B)4.05× 10^-9 Hz C)7.41× 10¹⁶ Hz D)4.5× 10^-26 Hz E)1.47× 10^-8 Hz

Question

Quizplus · Accepted Answer

The frequency (f) of a photon is given by the equation:

E = hf

where E is the energy of the photon, and h is Planck's constant. Rearranging the above equation to solve for f, we get:

f = E/h

Substituting the values given in the question, we get:

f = (4.91 × 10^-17 J) / (6.63 × 10^-34 J·s) = 7.41 × 10^16 Hz

Therefore, the correct answer is choice C with a frequency of 7.41 × 10^16 Hz.
