Answer:
halved
Explanation:
The velocity of the a wave is obtained by multiplying the frequency and wavelength.
[tex]v=f\lambda\\\Rightarrow f=\frac{v}{\lambda}\\\Rightarrow \lambda=\frac{v}{f}[/tex]
Where
v = Velocity
f = Frequency
[tex]\lambda[/tex] = Wavelength
The velocity here is constant. So, if the frequency is doubled the wavelength is halved.
