Спектры второго и третьего порядков в видимой области дифракционной решетки частично перекрываются друг с другом. Какой длине волны в спектре третьего порядка соответствует длина волны 700 нм в спектре второго порядка?
In order to determine the wavelength of the third order spectrum that corresponds to a wavelength of 700 nm in the second order spectrum, you will need to use the formula: λn = d(sinθn), where λn is the wavelength of the nth order spectrum, d is the grating spacing of the diffraction grating, and θn is the diffraction angle of the nth order spectrum. By rearranging the formula, you can solve for θ3 (the diffraction angle of the third order spectrum) by using the previously obtained value for θ2 (the diffraction angle for the second order spectrum) and the known value of 700 nm for λ2. Once you have solved for θ3, you can plug it back into the formula to solve for the corresponding wavelength of the third order spectrum. This will ensure that the spectra do not overlap and will allow for accurate measurements. Remember to use the appropriate units and to double check your calculations for accuracy.
