Answer:

[tex]f=2x10^8Hz[/tex]

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:

[tex]f=\frac{c}{\lambda }[/tex]

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

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

Best regards!

The frequency will be "[tex]2\times 10^8 \ Hz[/tex]".

Electromagnetic radiation:

Radiation which thus travels throughout waves as well as which has both electromagnetic energy.

The power of electromagnetic radiation could range from minimum to maximum. Radio waves, radiation, x-rays, and gamma radiation are all examples of electromagnetic radiation.

Given value:

Wavelength, [tex]\lambda = 1.25 \ m[/tex]

Speed of light, [tex]c = 3\times 10^8[/tex] m/s

The frequency be:

→ [tex]f = \frac{c}{v}[/tex]

By putting the values,

     [tex]= \frac{3\times 10^8}{1.25}[/tex]

     [tex]= 2\times 10^8[/tex] Hz

Thus the above response is right.
