A diffraction grating is to be used to find the wavelength of the emission spectrum of a gas. The grating spacing is not known, but a light of a known wavelength of $632\mathrm{.}8$ nm is deflected by $43\mathrm{.}2$ in the second order by this grating. Light of the wavelength to be measured is deflected by $36\mathrm{.}3$ in the second order. What is the wavelength of this light in nm$?$
