Viva questions on calibration of constant deviation spectrometer

Answer 1

Answer:

full explantation

Explanation:

This spectrometer is used to analyse the wavelengths of photons emitted by various chemical sources. Atoms of different chemical compounds emit light when they shed excess energy through electron orbitals. For example, sodium lamps have a clear spectral emission at wavelengths of 588.9 and 589.6 nanometres.
