What frequency of electromagnetic radiation has photons of energy 4.7 × 10^-25 J? (h = 6.626 × 10^-34 J ∙ s) A)710 kHz B)4.7 MHz C)710 MHz D)1.4 GHz

Question

Quizplus · Accepted Answer

The frequency of electromagnetic radiation can be determined using the equation:

E = hf

where E is the energy of a photon, h is Planck's constant, and f is the frequency of radiation. Rearranging this equation gives:

f = E/h

Substituting the values given in the problem, we get:

f = (4.7 × 10^-25 J)/(6.626 × 10^-34 J∙s) = 7.10 × 10^14 Hz = 710 MHz

Therefore, the best choice is C) 710 MHz.
