Question

What is the wavelength of a radiowave that has a frequency of 9.650 x10^7 Hz (cycles per second)?h = 6.6261 x10^-34 J/sc = 2.998 x10^8 m/s

Answer 1

Hello!!

For this, we only need frequency and speed, so for calculate we applicate formula:

$\boxed{\lambda = V/f}$

$\textbf{Being:}$

$\sqrt{}$ $\lambda = Wavelength = \ ?$

$\sqrt{}$ $V = Velocity = 2.998*10^{8} \ m/s$

$\sqrt{}$ $f = Frequency = 9,650*10^{7} \ Hz$

$\text{Then let's \textbf{replace it according} we information:}$

$\lambda = 2,998*10^{8} \ m /s / 9,650*10^{7} \ Hz$

$\lambda = 3.106 \ m$

$\textbf{Result:}\\\text{The wavelength of the radiowave is \textbf{3.106 meters}}$
