An explosion occurs at the end of a pier. the sound reaches theother end of the pier by traveling through three media: air, freshwater, and a slender metal handrail. the speeds of sound in air, water, and the handrail are 343, 1482, and 5040 m/s, respectively. the sound travels a distance of 135 min each medium.
(a) through which medium does the sound arrivefirst, second, and third?
watersteel handrailair (first)
handrailairfresh water (second)
watersteel handrailair (third)

(b) after the first sound arrives, how much later do the second andthird sounds arrive?
s (second sound)
s (third sound)
