An FM radio station broadcasts electromagnetic radiation at a frequency of 103.4 MHz (megahertz; MHz =106sâ€“1). Calculate the w

kap26 [50]

Answer:

$Wavelength=2.899\ m$

Explanation:

The relation between frequency and wavelength is shown below as:

$c=frequency\times Wavelength$

c is the speed of light having value $2.998\times 10^8\ m/s$

Given, Frequency = 103.4 MHz = $103.4\times 10^{6}\ Hz$ ( as 1 MHz = 10⁶ Hz)

Thus, Wavelength is:

$Wavelength=\frac{c}{Frequency}$

$Wavelength=\frac{2.998\times 10^8}{103.4\times 10^{6}}\ m$

$Wavelength=2.899\ m$

What is a nonpolar covalent bond?

Vlad1618 [11]

<u>Answer:</u> The correct answer is Option D.

<u>Explanation:</u>

A non-polar covalent bond is defined as the bond which is formed between the atoms having no difference in electronegativity values. For Example: $Cl_2,H_2$ etc..

In this bond, the electrons are shared equally and $\Delta EN$ value is equal to 0.

Hence, the correct answer is Option D.
