How do you add two sine waves with different phases?
g(t) = B sin(ωt + φ). h(t) = C sin(ωt + ψ). Note that this includes cosines as a special case since a cosine is a sine with phase shift φ = 90°.
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.
When two waves are added together in phase it results in a?
Constructive interference occurs when the maxima of two waves add together (the two waves are in phase), so that the amplitude of the resulting wave is equal to the sum of the individual amplitudes.
How do you combine two waves?
In general, when we combine two waves to form a composite wave, the composite wave is the algebraic sum of the two original waves, point by point in space [Superposition Principle].
