### If the frequency is doubled then for waves what would be the wavelength and vlocity?

Frequency = Velocity divided by wavelength. So if frequency is
doubled that means velocity is doubled but the wavelength is
halved.
You can see this by keeping wavelength a constant :
If Frequency =1 and Wavelength= 1
1= Velocity/1
Velocity=1
If Frequency =2 and Wavelength= 1
2= Velocity/1
Velocity =2
OR keeping Velocity constant:
If Frequency =1 and Velocity= 1
1= 1/Wavelength
Wavelength =1
If Frequency =2 and Velocity= 1
2= 1/Wavelength
Wavelength=1/2

### If the frequency is 2 cycles per second then what is the wavelength?

It is not possible to answer this question numerically because
the velocity of the wave also needs to be known. The three
following equations are equivalent. velocity = wavelength x
frequency wavelength = velocity / frequency frequency = velocity /
wavelength The correct unit for frequency is Hz (Hertz) although
this is the same as the old "cycles per second". Wavelength is
measured in metres and velocity in metres/second.
