Wavenumber for a radiation having 5800 A ~ … wavelength is x × 10 cm − 1 . The value of x is ________ (Integer answer)

v ˉ ( wave no. ) = λ 1 = 5800 × 1 0 − 8 cm 1 = 17241 OR 1724 × 10 cm − 1 ⇒ x = 1724

Wavenumber for a radiation having $5800 \tilde{A} \dots$ wavelength is $x \times 10 cm^{- 1}$ . The value of $x$ is ________ (Integer answer)

Answer:

1724

Solution:

$\overset{v}{ˉ} ($ wave no. $) = \frac{1}{λ} = \frac{1}{5800 \times 1 0 ^{- 8} cm} = 17241$ OR $1724 \times 10 cm^{- 1} \Rightarrow x = 1724$
