Magnetic resonance imaging MRI) is a much-used noninvasive diagnostic technique in medicine. The radio frequency photons used have energies of about 10^-7 eV. What wavelength does this correspond to? A) 12 nm B) 1.2 m C) 12 m D) 1.2 nm E) 120 m

Question

Quizplus · Accepted Answer

The energy of a photon is given by E = hc/λ, where h is Planck's constant and c is the speed of light. Solving for λ with E = 10^-7 eV gives a wavelength of approximately 12 meters.
