Question

If the frequency of a turning fork is 512hz and speed of sound is 350m/s then find how far sound travels while the turning fork makes 15 vibrations

Answer 1

v = f × λ
350 = 512 × λ
λ = 350 ÷ 512
λ = 0.68359375 m

Therefore, = 0.68359375 × 15 = 10.25390625 m

If it helps and is correct...plz mark as brailiest...and if it is wrong...then sorry..plz dont report

Answer 2

velocity =f*lambda
....350/512= 0.68...
15 frequency =0.68×15 =10.24m
