Diffracted angle of Transmission Gratings

This Calculator Will Help You To calculate The Diffracted Angle For A Given Incidence Angle Of Transmission Gratings

$\frac{[ sin(\theta_m) - sin(\theta_i)]}{N}$= $m \lambda$

Raster Line Density $N$; Incidence Angle $\theta_i$; Order $m$; Wavelength $\lambda$; Diffracted Angle $\theta_m$;
