Answer 1

velocity of sound wave is given by v=nλ where n is the frequency .

If we double the frequency the wavelength will be halved.

Well,we know
velocity=Wavelength×frequency

Since it is air,so the velocity reamins same.

Then,
the wave length must become half so that velocity remains same. i,e

Velocity=(wavelength/2)×2×frequency


$<b>Hence,wavelength becomes half</b>$
