Question

Pick the wrong statement:
Interference to occur:

• A. frequency of one wave should be equal to another
• B. amplitude of one wave should be comparable to that of another
• C. one wave must superpose on another
• D. frequency of two waves can never be same / equal

Answer 1

The correct option is D frequency of two waves can never be same / equal

Interference is a phenomenon in which two waves of equal frequencies and nearly equal amplitudes superpose on one another and produce a resultant new wave.
