Which outcome occurs when dual-frequency laser beams interfere?

💡 Explanation

Beat frequency generation occurs because interference between closely spaced frequencies leads to amplitude modulation at their difference (beat frequency); therefore the amplitude varies, rather than changing gain or waveguide modes without this specific superposition.
