Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

can anybody pls explain what is reduce the wave speed by factor of 2?

question:

original v(string) = 265m/s

F (tension) = 500N

m (mass) = 0.005kg

l (length) = 0.7m

Equation:

v = sqrt of [F / (m/l)]

therefore m = (F * l) / v square

but I though reduce speed by the factor of 2 = divided by 2?? pls kindly advise.

thanks
