If a solid line represents a covalent bond and a dotted line represents intermolecular attraction, which of these choices shows
blsea [12.9K]
<span>Generally, a hydrogen bond can be characterized as a proton shared by two lone electron pairs. It occurs when a hydrogen (H) atom, covalently bound to a highly electronegative atom such as nitrogen (N), oxygen (O), or fluorine (F), experiences the electrostatic field of another highly electronegative atom nearby.

   Among the choices in the bond (-N...H-O) one side of the Hydrogen is bonded to a highly electronegative atom with a lone pair (-N) and the other side is directly bonded with a highly electronegative atom (O-).

    So -N...H-O- shows a hydrogen bond.</span>

Question 22 A VHF television station assigned to channel transmits its signal using radio waves with a frequency of . Calculate
aleksklad [387]

The question is incomplete, here is the complete question:

A VHF television station assigned to channel transmits its signal using radio waves with a frequency of 66.0 MHz. Calculate the wavelength of the radio waves. Round your answer to 3 significant digits.

Answer: The wavelength of the radio waves is 4.54 m

<u>Explanation:</u>

To calculate the wavelength of light, we use the equation:

\lambda=\frac{c}{\nu}

where,

\lambda = wavelength of the light

c = speed of light = 3\times 10^8m/s

\nu = frequency of light = 66.0MHz=66.0\times 10^6s^{-1}

Putting the values in above equation, we get:

\lambda=\frac{3\times 10^8m/s}{66.0\times 10^{6}s^{-1}}=4.54m

Hence, the wavelength of the radio waves is 4.54 m
