Standing Waves Video Lessons

Concept

# Problem: A wave traveling on a Slinky® that is stretched to 4 m takes 2.4 s to travel the length of the Slinky and back again. (a) What is the speed of the wave? (b) Using the same Slinky stretched to the same length, a standing wave is created which consists of three antinodes and four nodes. At what frequency must the Slinky be oscillating?

###### FREE Expert Solution

(a)

Distance, speed, and time raltionship:

$\overline{){\mathbf{v}}{\mathbf{=}}\frac{\mathbf{d}}{\mathbf{t}}}$

d = 2L = 2(4m) = 8m

t = 2.4 s
