Do you mean phase changes in the earth which cause seismic reflections?

i think that's not related to the seismic reflection.

I want to know if there is any proofs of

"how do the wave speeds compare for the two strings?

From high speed to low speed (low density to high density)"

I don't have a reference off hand, but most textbooks on acoustics, vibration transmission, etc. should work through details of the maths.

can it be proved by momentum?

i can find them in the textbooks, but without the proofs
