Wavenumber for a radiation having 5800 Ao\mathop A\limits^o Ao wavelength is x×10 cm−1x \times 10 \mathrm{~cm}^{-1}x×10 cm−1 The value of xxx is ________. (Integer answer)
We are given the formula for wavenumber:
vˉ=1λ ⇒ 15800 × 10−8 cm−1\bar{v}=\frac{1}{\lambda} \Rightarrow \frac{1}{5800 \times 10^{-8}} \mathrm{~cm}^{-1}vˉ=λ1 ⇒ 5800 × 10−81 cm−1
Let's simplify the equation step by step:
⇒ 1085800 ⇒ 10658 \\ \Rightarrow \frac{10^8}{5800} \Rightarrow \frac{10^6}{58} \\ ⇒ 5800108 ⇒ 58106
⇒ 10000058 × 10 \Rightarrow \frac{100000}{58} \times 10 \\ ⇒ 58100000 × 10
⇒ 1724.13 × 10 \Rightarrow 1724.13 \times 10 \\ ⇒ 1724.13 × 10
⇒ 1724 \Rightarrow 1724 ⇒ 1724
Thus, the wavenumber is 1724 cm−11724 \mathrm{~cm}^{-1}1724 cm−1.
