It means how fast it advances.
The velocity of the wave
The speed the wave is traveling through space
The velocity of a point that moves with a wave at constant phase. Also known as celerity; phase speed; wave celerity; wave speed., wave velocity.
How quickly the wave travels
No.
Wavelength*Frequency = Velocity of the wave. or Wavelength/Period = Velocity of the wave.
Velocity and speed are not synonyms.
If u meant radio wave, then velocity of all electromagnetic wave is 3*108 m/s. Hence velocity of radio wave will be the same ,as it as an em wave, irrespective of its wavelength.
The velocity of a wave which maintains consatnt phase at all successive positions during propogation is known as wave velocity or phase velocity. The velocity of a group of waves which maintains constant poditions during the propogation is known as group velocity.
The speed and direction of a wave
Wave velocity
velocity = frequency x wavelength
