ocr: MDI The Sun resonates like a huge musical instrument. MCI Medliun- Puwer Speulrurn However, unlike a musical instrument that is tuned to a single trequency, the Sun resonates in tens of millions of ways all at the same time. The figure shows how much acoustic energy there is at each trequency for every one of the spatial modes of solar oscillation. The pitch U of the resonance depends on the physical conditions in 2 the interior of the Sun where the sound waves travel. So, the frequency of each mode reveals something about a ) 50 100 150 200 2 230 300 angular degree, slightly different part of ...
