Question

Four students, a, b, c, and d, in a group take 6m long slinky and produce a longitudinal wave, and they observe that in 10 seconds 4 waves completed on this observation. What is the speed of the wave in a slinky?

Answer 1

solution: there time = 10s

distance = 6m

total wave. = 4

time for one wave = 10/4

speed. =distance/time

so, speed = 6m/10se/4

= 6m×4/10se

= 2.4m/s
