Wavelength will decrease when the frequency will increase as lamda is inversely proportional to frequency
Now if frequency = x
So wavelength = y
Now, frequency = 2x
Wavelength = 1/2y
Now if frequency = x
So wavelength = y
Now, frequency = 2x
Wavelength = 1/2y

Velocity of Sound in air = 330 m/s approximately. It depends on factors like Pressure, temperature or density of air.
velocity = frequency * wavelength
v = f * λ
As the product of f & λ is a constant, if f is doubled, λ will become half of its value.
