After a photon is generated in the core of the sun, it travels a short distance and interacts with another particle. the interaction causes a photon to travel in a different direction. over large distances and many interactions, the photon's path resembles that of a stumbling drunk person. if a photon generated in the center of the sun's core can only travel about 0.02 cm before the next interaction, what is the minimum amount of times the photon will interact before reaching the convection zone? assume the diameter of the core is 25 percent of the sun's diameter and use the radius of the sun (6.96 × 108 m).

Two loudspeakers, 5.5 m apart and facing each other, play identical sounds of the same frequency. you stand halfway between them, where there is a maximum of sound intensity. moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.33 m . assume the speed of sound is 340 m/s. part a) what is the frequency of the sound? part b) if the frequency is then increased while you remain 0.21 m from the center, what is the first frequency for which that location will be a maximum of sound intensity? express your answer to two significant figures and include the appropriate units.
