Question

If wavelength is doubled and frequency is kept constant, how does this affect velocity of the wave?

Answer 1

wavelength* frequency = v
\[w _{0} * f_{0} = v_{0}\]
\[2(w_{0}) * f_{0} = 2v_{0}\]

Answer 2

velocity also gets doubled then

Answer 3

velocity is directly proportional to the wavelength

Answer 4

wavelength * freq = speed of wave. So if wavelength increases 2X and freq is constrant, then speed increases by 2X.

Answer 5

v=f*waelength...
so it gets doubled.
