AP EAMCET · PHYSICS · Waves and Sound
Two waves of frequency \(f\) and amplitude \(a\) superimpose with each other. The total intensity is directly proportional to
- A \(a\)
- B \(2 a\)
- C \(2 a^2\)
- D \(4 a^2\)
Answer & Solution
Correct Answer
(D) \(4 a^2\)
Step-by-step Solution
Detailed explanation
When two waves of same frequency \(f\) and having same amplitude \(a\) superimpose, then resultant amplitude, \(A=a+a=2 a\) Total intensity \(I\) of resultant wave is directly proportional to square of amplitude.…
