Why you are use monochromator in uv spectroscopy?
A monochromator in UV spectroscopy is used to isolate a specific wavelength (or range of wavelengths) of light from the UV region of the spectrum. This helps in achieving better wavelength selectivity and accuracy in UV spectroscopic measurements by allowing only the desired wavelengths to pass through to the sample.
Why must the slit width of a prism monochromator be varied to provide constant effective bandwidths but a nearly constant slit width provides cnstant bandwidth with a grating monochromator?
Prisms and gratings have different dispersive properties. Grating has a linear dispersion of wavelengths meaning the band on the focal plane varies linearly with the wavelength. Prisms are not linear, the shorter the wavelength the greater the dispersion. Thus, when a spectrum is being scanned, the dispersive device needs to rotates different amounts depending on whether it is prism or grating to focus light on the exit slit. If its grating, the slit width will need to be varied minimally; if it is a prism, the slit width will need larger changes as the dispersion gets greater.
What is Uv-vis spectrometer schmatic and block diagrams?
A UV-Vis spectrometer schematic typically includes a light source, monochromator, sample holder, detector, and data acquisition system. The block diagram shows the flow of light through these components to measure the absorption of light by a sample at different wavelengths. The light source emits a broad spectrum of light, which is then filtered by the monochromator to select a specific wavelength that passes through the sample and is detected by the detector to generate a spectrum.
What is the purpose of the planets other than the Earth?

What is the purpose of a bycicle?
The purpose of a bicycle is to help people get around.
What is the difference between monochromator and polychromator?
A monochromator is an optical device that transmits a single wavelength or narrow band of wavelengths of light, while a polychromator transmits multiple wavelengths or a broad range of wavelengths simultaneously. Monochromators are used to select specific wavelengths for experiments, while polychromators are used to analyze or measure a range of wavelengths in a single operation.
Which type of monochromator produces the purest monochromatic light in the UV range?
A prism monochromator typically produces the purest monochromatic light in the UV range. This is because prisms offer high light transmission with minimal dispersion, resulting in excellent spectral purity for UV light.

What are basic features of spectrometers?
The basic parts of a spectrophotometer are a light source, a holder for the sample, a diffraction grating in a monochromator or a prism to separate the different wavelengths of light, and a detector.
