Question

A radio operator broadcast on the 6 -Meter Band the frequency of this electromagnetic radiation is

Answer 1

Step-1: Given data

1. The wavelength of the electromagnetic radiation is $\lambda =6m.$

Step-2: Frequency of electromagnetic waves

1. Frequency is the number of complete waves produces in unit time.
2. The frequency of an electromagnetic wave is defined by the form, $\nu =\frac{c}{\lambda }$, where, c $\left(c=3\times {10}^{8}m/s\right)$ is the velocity of light in free space and $\lambda$ is the wavelength of the radiation.

Step-3: Finding the frequency

As we know, $\nu =\frac{c}{\lambda }$.

So,

$$\begin{gathered} \nu =\frac{c}{\lambda }=\frac{3\times {10}^8}{6}=0.5\times {10}^8 \\ or\nu =50\times {10}^{6}Hz. \end{gathered}$$

Therefore, the frequency of this electromagnetic radiation is $50\times {10}^{6}Hz.$
