the speed of radio waves in air is 3 x 10^8 m/s. what is the wavelength of radio waves having a frequency of 5 x 10^5 hz? :eek:

the speed of radio waves in air is 3 x 10^8 m/s. what is the wavelength of radio waves having a frequency of 5 x 10^5 hz? :eek:
wavelength = 299792458 divided by frequency
approx: 6000m
Thank you for posting your question to the Ask Me Help Desk!
A formula that you need to be familiar with here is...
Speed = Frequency x Wavelength
Where speed is measured in meters per second, frequency is measured in Hertz, and wavelength is measured in meters.
The speed of the wave as given in your problem is 3 x 10^8 m/s. If the wave has a frequency of 5 x 10^5 Hz we can then substitute these values in the appropriate place in the formula.
3 x 10^8 = (5 x 10^5) x (wavelength)
To solve, we can divide both sides by 5 x 10^5
This will give us a wavelength of 600 meters.
Apologies to all... doh!
Bad day at the races.
