The reactance (X_L) of an inductor is given by the formula X_L = 2πfL, where f is the frequency in hertz (Hz), L is the inductance in henries (H), and X_L is the reactance in ohms (Ω). Rearranging the formula to solve for frequency, we get f = X_L / (2πL). Substituting the given values (X_L = 5 Ω, L = 1.5 mH = 1.5 x 10^-3 H), we find f ≈ 530 Hz, which is 0.53 kHz.
