An oil tanker explodes in the sea. At that instant, an aircraft and a submarine were present vertically above and below the oil tanker respectively at equal distances from it. Find the ratio of the time taken by sound waves to reach them. (Speed of sound in air = 340 m/s. The speed of sound in seawater = 1520 m/s)
4.47
Let the aircraft and the submarine be ‘x’ m above and below the tanker respectively. Time taken by sound to reach the aircraft is tair=x340s
Time taken by sound to reach the submarine twater=x1520s
Ratio of the time taken
tairtwater=(x340)(x1520)=1520340=4.47
