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 wavelength λ, we find λ = hc/E. Substituting the given energy (10^-7 eV) and converting it to joules, we find the wavelength to be approximately 12 meters.
