Question

please dont copy someone else answer to the question. Also answer both parts of the question

PRE-LABORATORY QUESTIONS he zeroth-order, first-order, and second-order spectra a grating (state the determining conditions). Discuss the path-length differences in terms of the wavelength, λ, and the order number, m. How many wavelengths are contained in the path- length difference between the first and third orders? Draw a sketch to aid your explanation. (b) Explain how the different colored spectral lines are formed at higher order and not at zeroth- order. If we had used a laser-light source, what would the higher orders look like? Would it have different colored spectrum? Explain your reasoning. Note: lasers should NEVER be used in conjunction with the telescope of a spectrometer, as the focused light ray would absolutely damage the retina; instead, the diffracted laser light should be projected on a screen, as was done in Experiment XVII
