Two waves with similar frequencies are added. The resulting waveform oscillates with the average frequency and with an oscillating amplitude that changes with a frequency equal to the difference between the original frequencies. These oscillations in the amplitude are known as beats. The traces show the resulting waveforms that occur when two different pairs of waves are added. Graph is for the same time interval in both cases, which of the following statements is TRUE?

Question

G1 Physics · Accepted Answer

Step 1: Beat frequency is fᵦ = |f₁ - f₂|. Step 2: Use how loading, shortening, tension change or motion changes the unknown frequency. Step 3: Select the value consistent with the stated increase/decrease of beat frequency. Final: B: On average, the waves on the right had higher frequencies, but the difference between frequencies less..
