Upоn electrificаtiоn, hydrоgen produces а chаracteristic line spectrum consisting of four lines in the visible region of the electromagnetic spectrum. The light emitted in different regions of the visible spectrum corresponds to transitions from the third (n = 3), fourth (n = 4), fifth (n = 5), or sixth (n = 6) energy level down to the second (n = 2). Which transition corresponds to the red line in the hydrogen spectrum?A) n = 2 → n = 3B) n = 2 → n = 6C) n = 3 → n = 2D) n = 4 → n = 2E) n = 6 → n = 2
