The number of waves that are present in the unit distance is termed a wave number. The wave number and wavelength are related as:

$\mathbf{wave}鈥�\mathbf{number}\mathbf{=}\frac{\mathbf{1}}{\mathbf{wave}鈥�\mathbf{length}}$

The given wave number of a radiation is $1600鈥�c{m}^{-1}$.

The wavelength of the radiation can be determined by using the following formula:

$\begin{array}{rcl}wave鈥�length& =& \frac{1}{wave鈥�number}\\ & =& \frac{1}{1600鈥�c{m}^{-1}}\\ & =& 6.25脳{10}^{-4}鈥�cm\\ & =& 62500鈥�A掳\end{array}$

Hence, the wavelength of the given radiation is 62500 A^o.

The given wave number of a radiation is 3000 cm^-1.

The wavelength of the radiation can be determined by using the following formula:

$\begin{array}{rcl}wave鈥�length& =& \frac{1}{wave鈥�number}\\ & =& \frac{1}{3000鈥�c{m}^{-1}}\\ & =& 3.33脳{10}^{-4}鈥�cm\\ & =& 33300鈥�A掳\end{array}$

Hence, the wavelength of the given radiation is $\begin{array}{rcl}& & 33300鈥�A掳\end{array}$.

The given wave number of a radiation is 1715 cm^-1.

The wavelength of the radiation can be determined by using the following formula:

$\begin{array}{rcl}wave鈥�length& =& \frac{1}{wave鈥�number}\\ & =& \frac{1}{1715鈥�c{m}^{-1}}\\ & =& 5.83脳{10}^{-4}鈥�cm\\ & =& 58300鈥�A掳\end{array}$

Hence, the wavelength of the given radiation is 58300 A^o.

The given wave number of a radiation is 1750 cm^-1.

The wavelength of the radiation can be determined by using the following formula:

$\begin{array}{rcl}wave鈥�length& =& \frac{1}{wave鈥�number}\\ & =& \frac{1}{1750鈥�c{m}^{-1}}\\ & =& 5.71脳{10}^{-4}鈥�cm\\ & =& 57100鈥�A掳\end{array}$

Hence, the wavelength of the given radiation is 57100 A^o.

The given wave number of a radiation is 2220 cm^-1.

The wavelength of the radiation can be determined by using the following formula:

$\begin{array}{rcl}wave鈥�length& =& \frac{1}{wave鈥�number}\\ & =& \frac{1}{2200鈥�c{m}^{-1}}\\ & =& 4.54脳{10}^{-4}鈥�cm\\ & =& 45400鈥�A掳\end{array}$

Hence, the wavelength of the given radiation is 45400 A^o.

The given wave number of a radiation is 3300 cm^-1.

The wavelength of the radiation can be determined by using the following formula:

$\begin{array}{rcl}wave鈥�length& =& \frac{1}{wave鈥�number}\\ & =& \frac{1}{3300鈥�c{m}^{-1}}\\ & =& 3.03脳{10}^{-4}鈥�cm\\ & =& 30300鈥�A掳\end{array}$

Hence, the wavelength of the given radiation is 30300 A^o.
