Calculate the wavelength of radio waves if their frequency is 5x10^6Hz.
v=fλ
λ=v/f=(3 x 10^8)/(5x10^6)
= 60
So, my answer is 60. Is this correct?
Thanks for your help!!

60 is not a length. It is simply a number. If a number does not have units, it has no relationship with reality.
The correct way to do this is:
v = f*λ
λ = v/f
λ = (3*10^8 m/s)/(5*10^6 Hz)
λ = 60 m

Radio wave is an electromagnetic spectrum wave so it relatively is velocity is 3x10^8 m/s, you have the frequency so use V= F x C V= velocity F= frequency C = wavelength So 3x10^8 / ninety 3.1x10^6 = 3.22m

Your answer is correct, but don't forget the units! The answer is 60 meters.

Don't forget the units! 60m (or 60 meters/metres)
My physics teacher used to write in big fat red letters UNITS everytime I forgot to put them in my answers - now I never forget!
