Question

What is the wavelength for radio waves with frequency 3x10^9

Answer 1

Answer:

0.1 meters

Step-by-step explanation:

For an electromagnetic wave, the relationship between wavelength λ, frequency ν, and the speed of light c is given by:

$c=\lambda \nu$

where $c=3*10^8m/s.$

In our case of the radio waves $\nu=3*10^8$

therefore the wavelength λ is:

$\lambda=\frac{c}{\nu} =\frac{3*10^8}{3*10^9} =0.1m.$  

Therefore the wavelength of the radio waves is 0.1 meters.
