Question

A strong transverse horizontal pulse,created at one end of the string,is observed to complete 5 journeys along its length,before fading out.The intial reading of the stp clock used in the experiment was 5s and the final reading was 55s.If the lenght of string for one jouney is 'L'm,the speed of pulse,through the string is-----

Answer 1

l/10 m per s
first calculate the frequency and then speed

Answer 2

Answer:

Lenght = L

Total length = 5L

Initial time = 5s

Final time = 55s

thus, 55-5 = 50s

Speed  = distance/time

            = 5L/50

            = L/10 m/s

hope it helped u <3
