Question

One wave whose frequency is 256 hz propagating with a velocity of 330 m/s what will be speed of wave whose frequency is 512 hz propagating in same medium

Answer 1

speed=wavelength*frequency

330=wavelength*256

330/256=wavelength

1.28m=wavelength

speed=wavelength*frequency

speed=1.28*512(same medium)

speed=655.36m/s

Answer 2

$<h1 > heya$

$<h4 > answer...$

$v = f \times \gamma$

$330 = 256 \times \gamma$

$\gamma = \frac{330}{256} = 1.28m$

For the second wave,

$1.28 \times 512 = 655.36m pers$

Hope it helps you
