<u>Given:</u>
Frequency (ν) = 319 THz
<u>To determine:</u>
The wavelength corresponding to the given frequency
<u>Explanation:</u>
Wavelength (λ) and Frequency(ν) are related as:
λ = c/ν
where c = speed of light = 3*10⁸ m/s
Now:
SI unit of frequency is Hertz (Hz) also expressed as cycles per second
i.e 1 Hz = 1 s⁻¹
1 Terahertz (THz) = 10¹² Hz
therefore the given frequency ν = 319 *10¹² s⁻¹
λ = 3 * 10⁸ ms⁻¹/319 *10¹² s⁻¹ = 940 * 10⁻⁹ m
since 1 nanometer (nm) = 10⁻⁹ m
The wavelength is λ = 940 nm
Ans: The infrared wavelength = 940 nm
Answer:
tetrahedral
As carbon has no 4 valence electrons that are occupied by 4 chlorine atoms, we get 0 lone pair in carbon and sp3 hybridisation which leads to tetrahedral shape.
Answer:
PH. PH2. PH3.

It can form 3 bonds because 1 electron is in each of the 3 2p orbitals.
<span>The electron configuration of nitrogen (atomic number 7) is 1s2 2s2 2px1 2py1 2pz1 </span>
