Question: The wavefunction for a wave 1 0 points travelling on a taut string of linear mass density is given by: y ( x , t

The wavefunction for a wave

10

points

travelling on a taut string of linear mass density

is given by:

y (x, t) =

s i n (k x + t) .

If the speed of the wave is reduced by a factor of three, while keeping the same frequency, amplitude and linear mass density, then the ratio of the new power to the initial power is:
