Short Answer
A grating is to be used to find the wavelength of the emission spectrum of a gas.The grating spacing is not known,but light of a known wavelength of 632.8 nm is deflected by 43.2° in the second order by this grating.Light of the wavelength to be measured is deflected by 34.9° in the second order.What is the wavelength of the light that is to be measured?
