In This post you will get answer of Q.
The relation between frequency $upsilon$, wavelength $lambda$ and velocity of propagation of a wave $v$ is
Solution:
Velocity of the wave,
$v = upsilonlambda$ or $upsilon = frac{v}{lambda}$
Solution:
Velocity of the wave,
$v = upsilonlambda$ or $upsilon = frac{v}{lambda}$
