Ham radio operators often broadcast on the 6-meter band. The frequency of this electromagnetic radiation is MHz. [speed of light
Volgvan

Answer:

50 MHz

Explanation:

The relation between frequency and wavelength is shown below as:

c=frequency\times Wavelength

c is the speed of light having value 3\times 10^8\ m/s

Given, Wavelength = 6 m

Thus, Frequency is:

Frequency=\frac{c}{Wavelength}

Frequency=\frac{3\times 10^8}{6}\ Hz

Frequency=50\times 10^{6}\ Hz

Also,

Also, 1 Hz = 10^{-6} MHz

So,<u> Frequency = 50 MHz.</u>
