Answer:
velocity is now propotional to the wave length
Step-by-step explanation:
By definition
![velocity=frequency*wave.length](https://img.qammunity.org/2020/formulas/physics/middle-school/thf1t1312qizgi9y39xzh173rdhvgzyayr.png)
when the frequency is kept a constant ,
![velocity=k*wave.length](https://img.qammunity.org/2020/formulas/physics/middle-school/ma191mu0a9j1chqenoche52kn97yl2lodz.png)
velocity is now propotional to the wave length
(higher the wavelength , higher the velocity)
velocity ∝ wave length
