Best way of measurement sodium wavelength?

Click For Summary
SUMMARY

The most accurate method for measuring sodium wavelength is through a grating diffraction experiment, as confirmed by multiple participants in the discussion. Additionally, prisms were also utilized in undergraduate optics labs for similar measurements. The consensus indicates that while gratings are preferred for their precision, prisms remain a viable alternative for educational purposes.

In undergraduate optics lab we used prisms and gratings. For the lab report we were to answer that very question!
