Wave Exercise-4: Solution

A longitudinal wave traveling on a slinky (see figure below) has a period of 0.50 s and a wavelength of 25 cm.
Question 1: What is the frequency of the wave?
Solution:
f = 1 / T = 1 / 0.50 = 2 Hz

Question 2: What is the speed of the wave?
Solution:
v = f × λ = 2 Hz × 25 cm = 50 cm/s
