Question

In a certain gas, a source produces 40,000 compression and 40,000 rarefaction pulses in 1 sec. When the second compression pulse is produced; the first is 1cm away from the source. Speed of wave is .................... 1) 4000 m/s 2) 5000 m/s 3) 6000 m/s 4) 400 m/s

Answer 1

Explanation:

The answer is 50000 m/sec2

Answer 2

Answer:

that is 40,000 cms

Explanation:

because ,

frequency ×wave length = 40,000 × 1 = 40,000

so the answer this may be correct
