Aslinky 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.

what is the question because that is not a question.

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.
