Answer: The correct answer is "same frequency".
Explanation:
Resonance occurs when the natural frequency of the object matches with the applied frequency.
Standing wave is the stationary wave in which there is an interference of the wave moving in an opposite direction each having same frequency and same amplitude.
Resonance is the response of a standing wave to another wave when the frequency of the both waves are same.
Therefore, the answer is "Same frequency".
