[SOLVED] Same string, different mass per unit length, what's the wavelength?
*oddly I can't edit the original title?
A string is made of two materials of different mass per unit length. On the left side of the string, the mpu is given as well as its wavelength. On the right only the mpu. The question asks for the right side's wavelength.

I immediately began doing just a simple balancing equations. 2.76/20.4 = 3.63X
yet it returned the answer as incorrect. How can that be??
as well, I thought maybe it was trick question since its all the same single string, the wavelength must be the same. so I put 20.4 and as well it returned it as incorrect.
I'm really not sure what I did wrong.
