A periodic longitudinal wave that has a frequency of 20.0 Hz travels along a coil spring. If the distance between successive compressions is 0.400 m, what is the speed of the wave?(adsbygoogle = window.adsbygoogle || []).push({});

my answer:

T=1/f

T=1/20=0.05 sec

v=d/t= 0.400 meter/ 0.05 second= 8 m/s

there is other question but i couldn't figure it out because i don't know how i can use pulses to get frequency or period

the question is

A wave generator produces 16.0 pulses in 4.00 s.

a. What is its period?

b. What is its frequency?

can i know what pulse really mean, and if i am right by saying frequency will be 16/2=8 hertz
