Question

a longitudinal wave travels at a speed of 0.3 m/s and the frequency of wave is 20 Hz. Find the separation between the two consecutive compressions.

Answer 1

[tex]hy friend [/tex]



speed = V = 0.3 m/s
frequency = n = 20Hz
wave length = ?


speed = frequency× wave length
⇒V = n × wave length
⇒V/n = wave length
⇒0.3/20 = wave length
⇒3/10/20 = wave length
⇒3/10×1/20 = wave length
⇒0.015 metre = wave length
⇒so the separation between the two consecutive compression

= wave length = 0.015 metre.....
