velengths enters the mon\avelengths and reflects it towards a second mirror. Light reflects off the second mirror. One wavelength exits the monochromator and the other wavelength does not. It diffracts radiation into different wavelengths and disperses it at different angles. It refocuses the collimated radiation. It splits the radiation into parallel rays. It is what the refocused radiation of different wavelengths is focused onto. It is where monochromatic radiation leaves the monochromator. It is where polychromatic radiation from the source enters the monochromator. Answer Bank
