A slinky is stretched across a classroom and moved up and down at a frequency of 3 Hz. If the corresponding wave velocity is 6.6 m s , determine the wavelength of the slinky wave.
A) 0.45 m
B) 2.2 m
C) 9.9 m
D) 19.8 m

For any wave,  Wavelength = (speed) / (frequency).

So the Slinky Wavelength = (6.6 m/s) / (3 / sec)

Wavelength = 2.2 meters .

It takes the compression in the wave 2.2 seconds to travel the length of the classroom.
