How do the low-frequency sound waves associated with the 5-minute oscillations traverse the interior of the Sun?

Question

Quizplus · Accepted Answer

Low-frequency sound waves associated with 5-minute oscillations are known as p-modes or pressure modes. These sound waves travel through the interior of the Sun by following curved paths due to the variation in the solar density, temperature, and pressure. When they reach the underside of the solar surface, they are partially reflected and partially transmitted. The transmitted waves interfere with the incoming waves, resulting in standing waves that cause the Sun's surface to oscillate. Therefore, option C is the correct answer.
