Diffraction Grating

Diffraction Envelope Minima Condition: $b \sin(\theta) = m \lambda$

Maxima Condition: $d \sin(\theta) = n \lambda$

Number of Fringes in the Central Maximum of the Diffraction Envelope: $2 \left\lfloor \frac{d}{b} \right\rfloor + 1$

Lines per mm: 600 lines/mm

Wavelength (λ): 500 nm

Distance (cm): 200 cm

Note: Intensity profile is normalized to the maximum intensity.
