Respuesta :
The sum (or difference) of two solutions of the wave
equation is again a solution of the wave equation(superposition principle)
therefore the amplitude of resultant wave is 3+4= 7cm
therefore the amplitude of resultant wave is 3+4= 7cm
Answer:
7 cm
Explanation:
When the waves are super-posed their amplitudes are added algebraically to get the resultant amplitude.
resultant amplitude = 3+4 = 7cm
