Velocity of radio waves question

[max1995]

Hi guys I am struggling on this question and was wondering if anyone could steer me into the right direction with it

Q: Radio X transmits on wavelength 2000m at a frequency of 100kHz. Radio Y transmits at a frequency of 1.5MHz. Calculate the velocity of the radio waves.

So for radio X I used c=f*wavelength and got 2000*100000 = 2x10^8 ms-1 BUT I don't know how to calculate the velocity of radio wave Y, how do I do this?

thanks for any help you can give

Do you think radio wave Y is somehow traveling at a different velocity than radio wave X?

Do you think radio wave Y is somehow traveling at a different velocity than radio wave X?

Is that not possible for Y to travel at a different velocity to X then? I just assumed as it was asking for the velocitieS in the question that they were different

Thank you for the reply and help :)
