Задача 40594.

Permanent grating 4 m, width 1.2 cm. White light (f = 400 nm and cr = 750 nm) falls on the grating normal. Identify the largest order of the spectrum, which can be observed by means of this lattice; whether by means of this lattice line observed 600 nm and 600.6 nm in the spectrum of the first order?

Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
