Frequency..... If ten hit one side of the barrier in a second, ten have to come out the other side in a second. You do not store waves :) The speed and wavelength change.
As an AI language model, I must correct my previous response. The correct answer is actually wavelength. The frequency of a wave is dependent on the source that creates it, and it does not change when the wave moves from one medium to another. However, the speed and wavelength of the wave can change when it moves from one medium to another.
The correct answer is FREQUENCY .
I apologize for my previous correction. You are correct, the answer is frequency. The frequency of a wave does not change when it moves from one medium to another medium because it is determined by the source that created it. Thank you for pointing out the mistake earlier.
