Kryger [21]

Answer:

$f=2x10^8Hz$

Explanation:

Hello!

In this case, given that frequency of the electromagnetic radiation showing off a wavelength of 1.25 m is computed by using the speed of light as shown below:

$f=\frac{c}{\lambda }$

We plug in the wavelength and speed of light to obtain:

$f=\frac{3x10^8m/s}{1.25m } \\\\f=2x10^8Hz$
