Question

A person standing between two vertical cliffs produces a sound. Two successive echoes are heard at 6 s and 8 s. Calculate the distance between the cliffs. (Speed of sound in air = 320 m/s) [Hint: The first echo will be heard from the nearer cliff and the second echo from the farther cliff.] *​

Answer 1

Answer:

2240 m

Explanation:

speed of sound =320m/s

sound travel towards first cliff =(6*320)/2 =960m

sound travel towards second cliff=(8*320)/2 =1280 m

total distance =960+1280=2240m

so distance between cliff =2240m
