When sound waves of the same frequency interact, they amplify. Sound waves of different frequencies cancel each other out. Where does the energy go when they cancel?

Sound wave interaction refers to the way in which sound waves behave and interact with their surroundings. This can include phenomena such as reflection, refraction, diffraction, and interference.
Sound waves reflect off of surfaces in a similar way to light waves. When a sound wave hits a surface, it bounces back at an angle equal to the angle at which it hit the surface. This is why we can hear echoes in large open spaces.
Sound wave interference occurs when two or more sound waves meet and interact with each other. This can result in constructive interference, where the waves combine and become louder, or destructive interference, where the waves cancel each other out and become quieter.
The Doppler effect is the change in frequency of a sound wave as the source of the sound moves closer or further away. This can affect sound wave interactions by causing a change in the perceived pitch of the sound.
Understanding sound wave interactions is crucial in many fields, such as acoustics, audio engineering, and medicine. It allows us to create better sound systems, design buildings with better acoustics, and use sound waves for medical imaging and treatment.
