a source of sound is placed at one end of an iron bar 2km long and 2 sounds are heard - Science - Sound

Question

a source of sound is placed at one end of an iron bar 2km long
and 2 sounds are heard at the other end at an interval of 5 6 s if
the velocity of sound in air is 330m/s , find the time taken by
sound to travel 2 km in iron and the velocity of sound in iron

nitish.gupta · Accepted Answer

Given that Speed of sound in air (V a ) = 330 m/s Speed of sound in iron Vi = ? Distance L = 2 km = 2000 m Let t 1 = Time taken by sound in air t 2 = Time taken by sound in iron (1) Î”t = t 1 â€“ t 2 = 5 6 s Now, $t_{1} = \frac{L}{V_{a}} = \frac{2000}{330} = 6 065$ t 2 = t 1 â€“ Î”t = 6 06 â€“ 5 6 = 0 46 s (2) $V_{i} = \frac{L}{t_{2}} = \frac{2000}{0 46} = 4348 m/s$

a source of sound is placed at one end of an iron bar 2km long and 2 sounds are heard at the other end at an interval of 5.6 s. if the velocity of sound in air is 330m/s , find the time taken by sound to travel 2 km in iron and the velocity of sound in iron.
