Sound waves only

Light waves only

Both light and sound waves

Neither sound nor light waves

Correct Answer

Both light and sound waves

Detailed Explanation

Interference is a phenomenon that can occur in both light waves and sound waves. Therefore, the correct answer is option 3: "Both light and sound waves." Interference is a characteristic of wave behaviour, and it occurs when two or more waves superpose, leading to the addition or subtraction of their amplitudes at specific points in space, resulting in a pattern of constructive and destructive interference.
