Two waves of same frequency and intensity superimpose with each other ...
Superposition of Waves in Opposite Phases
When two waves of the same frequency and intensity superimpose with each other in opposite phases, they interfere destructively. This means that the crests of one wave align with the troughs of the other wave, resulting in a cancellation of amplitudes.
Effects on Intensity and Frequency
- The intensity of the resulting wave after superposition does not increase. In fact, it decreases due to destructive interference.
- The frequency of the resulting wave remains the same as the frequency of the two waves that were superimposed.
Therefore, the correct answer is option D, "None of these." The intensity does not increase by 4 times or 2 times, and the frequency does not increase by 4 times. The superposition of waves in opposite phases leads to a decrease in intensity due to destructive interference, and the frequency remains unchanged.
