Adding two waves that have different frequencies but identical amplitudes produces a resultant x = x1 + x2. More specifically, x = Xcos(2π f1t) + Xcos(2π f2t).

What happens when two waves of different frequencies are added together?
Answer and Explanation: If two waves of different frequencies are propagating in the same direction are added together, their amplitudes would alternately add up and cancel out. In words, alternating constructive and destructive interferences would occur. As a result, they would form wave packets known as beats.
How do you add two signals with different frequencies?
You can go that in algebra: g(t) = f1(t) + f2(t). There you are, it is done. If you know what the signals are you can do it in time domain or in frequency domain. If they were more comoicared, then use Fourire too make them into sine waves and then combine them.
Can two waves with different frequencies interfere?
Beat frequency occurs when two waves with different frequencies overlap, causing a cycle of alternating constructive and destructive interference between waves.
Can two waves with different frequencies be in phase?
To be "in phase", the angular velocity of the two signals must be the same. The only way to do that is to have both frequencies the same.
