Maybe waves and sound isn't my niche, but I'm having severe difficulties with this stuff. I got a scaled score of 8-9 on the Waves passages, and am only on the second passage of the Sound chapter, and am finding it difficult... Anyways, can anyone please elaborate on the explanation to question 11 of passage 2 of the sound section? I don't understand what a "double Doppler shift" is, when, and why/how it happens... Please, help me someone... :scared:
